SUMMARY:2025 Shaw Lecture - Smart City Digital Twins: Toward More Sustainable\, Resilient\, and Livable Cities
DESCRIPTION:Smart City Digital Twins: Toward More Sustainable\, Resilient\, and Livable Cities\nMarch 3\, 2025\n3:00-4:30pm\, followed by a reception\nDuke Energy Hall\, Hunt Library \nJohn E. Taylor\, PhD\, NAC\nFrederick Law Olmsted Professor\nAssociate Chair for Faculty Development and Research Innovation\, Civil and Environmental Engineering\nGeorgia Tech \nABSTRACT:\nReports by the National Academies in the United States have encouraged investment in developing a more comprehensive understanding of network dynamics at the intersection between human and engineered networks. Concurrently\, cities are addressing rapid urbanization challenges by implementing socio-technological changes in their infrastructure systems as they evolve toward becoming smarter cities. The success of such an evolution\, however\, relies on solutions that can combine data from individual infrastructure components to urban scale networks. A great deal of research has focused on developing an understanding of data analytics at the scale of the city and of individual infrastructure components. However\, there is a gap in our understanding\, data collection approaches\, and analytical methods to integrate and visualize such disparate data and complex network dynamics. This presentation will describe efforts to formalize and implement a Smart City Digital Twin platform\, with an emphasis on efforts to understand\, model\, and improve energy consumption and disaster mobility across spatial scales in cities\, to foster more sustainable\, resilient\, and livable cities. \nPRESENTER BIO:\nDr. John E. Taylor is the inaugural Frederick Law Olmsted Professor of Civil and Environmental Engineering at Georgia Tech\, where he currently serves as the Associate Chair for Faculty Development and Research Innovation in the School of Civil and Environmental Engineering. Dr. Taylor received his PhD from Stanford University in 2006. At Georgia Tech\, he is founder and Director of the Network Dynamics Lab\, which focuses on; (1) achieving sustained energy conservation by coupling energy use with occupant networks and examining inter-building network phenomena in cities\, and (2) understanding and improving response times by affected human networks during extreme events in urban areas. Dr. Taylor’s research has received over $8M in funding from the National Science Foundation\, the Department of Energy\, the Alfred P. Sloan Foundation\, and other public and private funding sources. His research was awarded the National Science Foundation’s CAREER Award in 2011. In 2020\, Dr. Taylor was elected into the National Academy of Construction for his research and pedagogical efforts to improve urban sustainability and resilience and guide the evolution of smart cities. Dr. Taylor has authored over 250 technical publications\, won five journal best paper awards\, and founded two technology startups.

SUMMARY:EWC Seminar by Meredith Martinez (Jacobs) - What's in Your Toolkit?
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 3301 \nWhat’s in Your Toolkit? \nAbstract: Water reuse is a necessary part of creating sustainable water systems that will provide water for generations to come. Groundwater plays a fundamental role in the One Water initiative\, and maintaining resilient aquifer systems is a crucial factor in managing water systems in light of the various driving forces for water reuse (e.g.\,  water scarcity\, population growth\, climate change\, etc.). This presentation focuses on two water reuse projects and the experimental and modeling methods related to those projects. The first project\, the Sustainable Water Initiative for Tomorrow (SWIFT) project\, is an aquifer long-term replenishment (ALTR) project that uses continuous recharge into the multi-layered confined aquifer system to restore the potentiometric surface over space and time and increase storage in the system. The SWIFT Research Center (SWIFT-RC) is a 1 million gallon per day (MGD) demonstration facility in Suffolk\, Virginia that recharges the PAS through a multi-screen well. Addressing research questions about the impact of continuous\, sustained recharge on aquifer systems is crucial to the long-term sustainability of an ALTR project. Quantifying how flow moves through the multi-layered system is necessary to communicate travel times and water quality impacts on the aquifer system. This work uses injectate as an intrinsic tracer\, an in-situ flowmeter\, and a bromide tracer test to evaluate how flow is distributed through the eleven screens in the recharge well and to assess how flow distribution changes over time. Typically\, flow distribution in multi-screen wells is estimated only once over the length of a project and assumed to remain constant for modeling purposes; by measuring flow distribution using multiple methods over the course of the project\, this work shows that flow distribution is not constant. In future ALTR projects\, developing a consistent and robust monitoring plan to use injectate as an indicator of movement through the aquifer system\, paired with other methods to monitor changes in flow distribution\, will be a critical part of effectively evaluating how flow moves through the groundwater system. The second project\, Aquifer Recharge for Beneficial Reuse in Northeast Florida\, is a OneWater concept where Jacobs proposes using the natural system to recharge the Floridan Aquifer System (FAS) in response to Senate Bill 64\, which requires utilities to form plans to eliminate non-beneficial to surface water discharge. The conceptual modeling related to this project builds on an existing groundwater model of northeast Florida and southwest Georgia to evaluate the feasibility of a large-scale recharge to an area in the Lake Region north-central Florida. Potential recharge benefits are shown to be wide-ranging. \nBiography: Dr. Meredith Martinez is a civil engineer by training (BSCE NCSU\, 2017)\, focusing primarily on groundwater and hydrogeology. Her doctoral degree work in civil engineering (Virginia Tech\, 2022) focused on groundwater dynamics and transport modeling through complex\, multi-layered aquifer systems during managed aquifer recharge via injection wells. She has experience using experimental methods such as intrinsic tracers\, in-situ flowmeters\, and artificial tracers. Her work with Jacobs has expanded into computational modeling and creating solutions for clients using indirect potable reuse technologies. She is excited about the growing area of water reuse\, managed aquifer recharge\, and the use of innovative technologies to make our water resources sustainable.

SUMMARY:EWC Seminar by Detlef Knappe - Per- and Polyfluoroalkyl Substances in Drinking Water: Community Impacts and Interventions to Reduce Human Exposure
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 3301 \nPer- and Polyfluoroalkyl Substances in Drinking Water: Community Impacts and\nInterventions to Reduce Human Exposure\n \nAbstract: Some of the nation’s highest concentrations of per- and polyfluoroalkyl substances (PFASs) occur in the Cape Fear River basin of North Carolina (NC). This watershed is the largest in NC and serves as a source of drinking water for about 1.5 million people. In addition to commonly studied perfluoroalkyl acids\, a range of perfluoroalkyl ether acids (PFEAs)\, including GenX\, are important contaminants. PFEAs are byproducts generated during the manufacture of fluoropolymer building blocks. A fluorochemical manufacturer located in the central region of the watershed released PFEAs into the air and into surface water for almost four decades. PFEA levels in a 2015 sample of Cape Fear River water at the drinking water intake for Wilmington (NC) and surrounding communities exceeded 100\,000 ng/L\, and PFEAs passed through water treatment plants unabated. For the majority of the PFEAs\, which were identified by high-resolution mass spectrometry\, no information was available about their toxicity\, environmental behavior\, and removal by water treatment processes. In this presentation\, I will describe the impacts of PFEA contamination on NC communities\, responses by the NC Departments of Environmental Quality as well as Health and Human Services\, responses by drinking water providers\, and results of ongoing research designed to develop the science needed to reduce exposure and answer community questions. \nBiography: Detlef Knappe is the S. James Ellen Distinguished Professor of Civil\, Construction\, and Environmental Engineering at NC State University. He received his BS\, MS\, and PhD degrees from the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign\, and he joined the NC State faculty in 1996. He is the Deputy Director of NC State’s Superfund Center “Environmental and Health Effects of PFAS” and is a member of NC State’s Center for Human Health and the Environment. Detlef’s research interests broadly encompass drinking water quality and treatment. He is a member of the North Carolina Secretaries’ Science Advisory Board and serves as Associate Editor for AWWA Water Science.

SUMMARY:EWC Seminar by Asmita Narode - Methods to measure heat generation from ash in landfills
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 3301 \nMethods to measure heat generation from ash in landfills\n \nAbstract: In recent years\, there have been reports of a few municipal solid waste landfills experiencing temperatures as high as 100ºC. These landfills are referred to as elevated temperature landfills (ETLFs). ETLFs require increased monitoring and management. A recently published landfill heat accumulation model identified reactions that contribute significant heat to landfills\, including the hydration and carbonation of Ca-containing wastes such as ash. Model predictions were based on published information on reaction thermodynamics and kinetics. However\, there is limited data on heat evolution from ash. This study aims to develop laboratory methods to measure heat evolution from Ca-containing ash under landfill-relevant conditions (presence of water and abundance of CO2). A semi-adiabatic reactor system was developed. The reactor consists of four major parts: an insulated container (dewar flask)\, insulation\, a sample container\, and a center channel to hold a temperature sensor. The temperature sensor is connected to a data acquisition device (LabJack). The reactor is characterized for heat loss so that temperature data during ash reaction can be used to calculate the rate and extent of heat generation. Reactor characterization involves the determination of two parameters; the coefficient of heat loss and the thermal capacity. Validation experiments were conducted by measuring heat evolution from the hydration of pure CaO and the carbonation of pure Ca(OH)2 and comparing those to theory. In the case of Ca(OH)2\, a continuous stream of N2/CO2 was provided\, and the CO2 uptake was compared to theoretical expected uptake. Heat evolution and CO2 uptake data were used to calculate the heat generation rate. This heat and rate will be used to better parameterize models of heat generation and accumulation in landfills. The coefficient of heat loss and thermal capacity was measured to be 105 J‧hr-1‧K-1 and 1200 J‧K-1\, respectively. The validation experiments yielded an efficiency between 103 and 106% for hydration and between 104 and 107% for carbonation\, respectively. Work is in progress to parameterize the landfill model. \nBiography: Asmita Narode is a Ph.D. student working with Dr. Morton Barlaz at NC State. Her work focuses on measuring heat generation from ash that is disposed of in landfills. She completed her undergraduate in Civil Engineering in India and her M.S. in environmental engineering at Georgia Tech. Before starting her Ph.D.\, Asmita worked for a consulting firm.

SUMMARY:EWC Seminar by Christina Quaassdorff (Technical University of Madrid) - Modelling road transport emissions: a microscale point of view
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 3301 \nModelling road transport emissions: a microscale point of view \nAbstract: Road transport is often the main source of air pollution in urban areas worldwide. Many efforts have been aimed at reducing emissions from this sector achieving significant abatements. Nevertheless\, emission reductions have been lower than expected due to the heavy growth of transport in the last decades. To estimate emissions from the road transport sector\, there are several methods and approaches that are useful for different scales of analysis. To understand the spatial and temporal distribution of the emissions\, typically\, regional traffic emission models are used for the compilation of urban inventories\, and usually\, those are the most detailed data available at the city scale. This level of detail is not enough to understand the high pollutant concentrations that occur in specific urban highly polluted areas (hotspots). In recent years many actions have been undertaken to solve air quality problems in these traffic hotspots. But\, to accurately understand the influence of these very local high concentrations on the real exposure of the population\, there is a need to estimate the contribution of road traffic to atmospheric emissions in great detail (at microscale) for those areas. In this seminar\, we will dive into the capabilities of currently available road traffic emission modeling tools as well as some practical applications of those tools to support emission analysis at the microscale level.\n \nBiography: Christina Quaassdorff\, PhD\, is a visiting postdoctoral research scholar at NC State University coming from the Technical University of Madrid in Spain. She is a road traffic emission modeler that finished her Ph.D. in Environmental Engineering in 2018 with her dissertation about road traffic emissions modeling and air quality measures applied to Madrid in Spain. For two years\, she worked on technical support for the Spanish Ministry for Ecological Transition in order to achieve the Spanish commitments to the European Union’s air pollution reduction goals for 2030. Now\, she is collaborating with NCSU to estimate highly detailed road traffic emissions at city scale in the frame of an IRTEMS European Union grant.

SUMMARY:EWC Seminar by Daniel Westervelt (Columbia University) - Air pollution and climate change in Africa: From low-cost sensors to supercomputers
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 2331 \nAir pollution and climate change in Africa: From low-cost sensors to supercomputers \nAbstract: In Africa\, air pollution exposure has been linked to 1 million premature deaths annually and\, without intervention\, these numbers are likely to climb. Sparse pollutant monitoring across the continent makes these estimates uncertain and also hinders the development of mitigation policies and regulations. Additionally\, some of the most severe climate impacts are also felt in Africa\, despite the continent’s relatively small contribution to global greenhouse gas emissions. This talk will highlight some recent efforts to close the air pollution data gap in Africa using a variety of methods spanning from traditional reference monitors\, to consumer-grade low-cost sensors\, to satellite retrievals\, and to air quality and climate models. In particular we demonstrate the effectiveness of well-calibrated low cost particulate matter sensors in several previously-unmonitored megacities including Kinshasa (DRC)\, Lomé (Togo)\, Accra (Ghana)\, Nairobi (Kenya)\, and more. We find that many consumer-grade Plantower-based low-cost PM2.5 monitoring devices\, such as PurpleAir\, Clarity\, and QuantAQ\, perform well (r-squared ~ 0.6\, MAE ~ 7 µg m-3) compared to locally available reference monitors\, but can be improved dramatically (r-squared ~ 0.8\, MAE ~ 2) using a variety of statistical methods\, including linear regression\, random forest regression\, and Gaussian mixture regression. These well-calibrated sensors form the basis of dense urban networks of PM2.5 monitors in several African megacities\, for example in Kinshasa (DRC)\, where the annual mean PM2.5 in 2019 was approximately 45 µg m-3\, or ~8 times the WHO annual guideline. This talk will also present some research that leverages well-calibrated low-cost sensors and reference monitors to evaluate and improve the Africa region GEOS-Chem nested high-resolution model (25km x 25km). We also demonstrate the potential of fusing satellite data with ground-based observations using machine learning to develop high spatiotemporal resolution PM2.5 datasets\, which may be useful in policy and health settings in addition to model evaluation. Finally\, I will present climate modeling results that quantify how both local and remote aerosol emissions changes can have a substantial impact on African climate\, in particular rainfall in the drought-stricken Sahel region of Africa.\n \nBiography: Daniel Westervelt is currently a Lamont Assistant Research Professor at Columbia University’s Lamont Doherty Earth Observatory in Palisades\, NY.

SUMMARY:EWC Seminar by Ricardo Morales (Universidad de los Andes): Air quality challenges in Northern South America; From the synoptic to the micro scale
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 2331 \nAir quality challenges in Northern South America: From the synoptic to the micro scale \nAbstract: The processes shaping air pollution span many spatial scales. In the large and densely populated cities of Latin America\, one of the most rapidly urbanizing areas in the world\, day-to-day exposure to particulate pollution is often dominated by mobile sources in the near-road environment. However\, the seasonality of air pollution in the region is controlled by the long-range transport of smoke plumes from wildfires and agricultural burns. In this talk\, we will discuss how\, by using modeling and observational tools\, we can better understand the nature of air pollution in Northern South America\, identify its more pressing challenges\, and characterize the rapid transformations it is currently undergoing. This research helps identify opportunities to implement interventions to effectively improve air quality in the region. \nBiography: Ricardo Morales is an Associate Professor in the Department of Environmental Engineering at Universidad de los Andes\, in Bogotá\, Colombia. After graduating with a BS in Physics and in Chemical Engineering\, he completed his PhD in Atmospheric Sciences from Georgia Tech. Since then\, his research at Universidad de los Andes has used modeling and observational tools for atmospheric aerosols to better understand air quality in the northern portion of South America\, and the city of Bogotá in particular. He has authored over 20 peer-reviewed publications. He is currently visiting NCSU supported by a Fulbright Visiting Scholar grant.

SUMMARY:EWC Seminar by Francis de los Reyes (NCSU): An Engineer Talks About Poop
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nFitts-Woolard Hall 2331 \nAn Engineer Talks About Poop (Alternatively\, Challenges and Opportunities in Global Sanitation) \nAbstract: Most people don’t think about or don’t want to think about what happens to human waste- fecal material. Where do we poop\, where does it go? This is a big\, global problem: 2020 WHO/UNICEF data show that 3.6 billion people- 46% of the global population- don’t use a toilet or latrine where the fecal material is safely treated and disposed. This is a wicked problem that touches on engineering\, public health\, social and cultural dimensions\, and has economic impacts in less developed countries. This presentation will discuss a systems view of the sanitation “value” chain- from the user interface\, the toilet or latrine\, to the collection and transport of fecal material\, to treatment and disposal. Key factors for addressing this global challenge will be discussed\, including how to re-think sanitation technologies. \nOne major project is developing a hygienic and dignified way of emptying pit latrines. Every day\, pit latrines receive an estimated 0.6 billion kg of faeces and 2.1 billion kg of urine from 1.77 billion people around the world. Once pits are full\, fecal sludge has to be removed\, before being transported and treated/reused. Manual emptying of pit latrines using buckets and shovels still exist today – a high-risk\, unsanitary\, and undignified job. One of the biggest challenges in this field is developing a single pit emptying technology that can empty trash-filled pits at a competitive cost. Our NC State University team has developed the innovative pit-emptying device\, the Flexcrevator. This device removes fecal sludge even in the presence of trash in pits. The Flexcrevator system has been developed over 6 years with extensive field testing in South Africa\, Zambia\, Malawi\, Kenya\, and India\, with funding from the Bill & Melinda\nGates Foundation\, and has recently been patented. Our overall goal is to demonstrate how the Flexcrevator can scale-up to meet global demand for hygienic and profitable pit emptying\, thereby improving sanitation practices and access world-wide. The presentation includes the design evolution of the trash exclusion head\, lab testing results with faecal sludge simulants and trash\, and field testing results from Zambia\, Kenya\, Madagascar\, and Rwanda. The challenges and lessons learned in designing this technology will be discussed. \nBiography: Francis de los Reyes is the Glenn E. and Phyllis J. Futrell Distinguished Professor #2 of Civil\, Construction\, and Environmental Engineering\, Alumni Distinguished Undergraduate Professor\, and University Faculty Scholar at North Carolina State University. He is also an Associate Faculty of Microbiology and Training Faculty of Biotechnology. He has also worked in water and sanitation issues in developing countries\, and has collaborations in the Philippines\, India\, China\, South Africa\, Pakistan\, Ghana\, and Malawi. Current and past research projects include: competition between filaments and floc-formers in activated sludge\, ecophysiology of nitrifiers and denitrifiers in microbial floc\, N removal from swine waste\, fate of bioagents in landfills\, microbial characterization of landfills\, molecular techniques for groundwater remediation sites\, foam control methods\, factors affecting fats\, oils\, and grease deposits in sewers\, wastewater treatment for rural areas\, water reuse systems\, novel molecular techniques for detecting denitrifiers\, energy from co-digestion\, and solutions for pit latrine emptying problems.

SUMMARY:EWC Seminar: Following the Microbes in Maputo\, Mozambique: The Maputo Sanitation Trial
DESCRIPTION:Following the Microbes in Maputo\, Mozambique: The Maputo  Sanitation Trial  \nSpeaker: Drew Capone\, Ph.D.\, Post-Doc\, Department of Environmental Sciences and Engineering\, UNC-Chapel Hill \nSummary: The Maputo Sanitation (MapSan) Trial is a controlled before-and-after evaluation of a shared onsite  sanitation intervention in urban Maputo\, Mozambique. Intervention compounds (i.e.\, clusters of  households) received a pour flush to septic tank system with a soakaway pit for subsurface infiltration  of aqueous effluent\, while control compounds continued using existing shared sanitation. During trial  baseline and the 12-month and 24-month follow-up periods we collected soils\, flies\, and fecal  sludges from the living environment of trial compounds. We evaluated samples using culture\,  microscopy\, and molecular methods to evaluate the impact of the intervention on environmental fecal  contamination and advance our understanding of the fate and transport of enteric pathogens in low income urban environments. We found that the intervention reduced the presence of some fecal  contamination in the domestic environment\, but pathogen detection remained prevalent 24 months  following the introduction of new latrines. Using quantitative microbial risk assessment\, we estimated  infection risk from exposure to fecally contaminated soils was high for infants and children. Modelling  source apportionment of fecal wastes suggested that the daily transport of small quantities of child  feces or infrequent transport of moderate amounts of fecal sludges could plausibly explain observed  fecal contamination in soils. Together\, these results suggest a sustainable environmental response to  the risks posed by fecal-oral pathogens in low-income urban settings will require policies and  strategies capable of achieving a nearly complete reduction in the feces transported to the living  environment. \nJoin in person at Fitts-Woolard Hall Room 2321 or virtually via Zoom: go.ncsu.edu/ewcseminar \n  \nThis is a joint presentation from Environmental Water Resources and Coastal Engineering Seminar NC State University Global WaSH Cluster Speaker Series

SUMMARY:EWC Seminar: Waves Through Aquatic Vegetation: Flow-Vegetation Hydrodynamics and Sediment Transport
DESCRIPTION:Abstract: Aquatic vegetation alters the flow and sediment mobility within and around them\, shaping coastal environments in the long term. Improved sediment transport relations for vegetated flows become fundamental for predicting sediment transport rates through aquatic coastal ecosystems. We investigate suspended sediment transport under flow-vegetation hydrodynamics in oscillatory boundary layers. We conduct experiments in a U-shaped oscillatory tunnel using optical techniques\, including 2D and 3D particle image velocimetry. We explore how aquatic plants change the near-bed and in-canopy hydrodynamics from the single-plant scale to the vegetation patch scale. For a single plant\, we study the effect of vegetation morphology (shape and biomechanics) on the turbulence characteristics. We focus on the vegetation drag at the canopy top and near the bed to explore the flow-vegetation hydrodynamics. For sediment experiments\, we evaluate the impact of vegetation on the suspended sediment transport mechanisms. These various boundaries inform for a better assessment of the role of aquatic vegetation as eco-engineers in wave-dominated environments.\n\nBio: Jorge San Juan is a postdoctoral associate at St. Anthony Falls Laboratory in the Department of Civil\, Environmental\, and Geo-Engineering at the University of Minnesota Twin Cities.

SUMMARY:EWC Seminar by Liang Liu (CARB):  An overview of California’s 2020 mobile source strategy in the off-road sector
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nVirtual seminar: https://ncsu.zoom.us/j/96075468552?pwd=RlZvb2x2YmM3c25KQWdRaXNEdVhUUT09 \n An overview of California’s 2020 mobile source strategy in the off-road sector \nAbstract: The California Air Resources Board (CARB) 2020 Mobile Source Strategy (MSS) is a strategy document that illustrates the technology mixes needed to reduce emissions from California’s transportation sector. This includes cars\, trucks\, trains\, ships\, aircraft\, and all other on-road and off-road equipment. The MSS explores technologies for California to meet its various clean air goals including federal ambient air quality standards\, community risk reduction\, and ambitious mid- and long-term climate change targets. This presentation focuses on the control strategy in the off-road sector. Off-road covers a wide range of sectors including locomotives\, ocean-going vessels\, commercial harbor craft\, construction and mining\, lawn and garden\, aircraft and many other industries. Off-road engines are significant sources of air pollutants such as nitrogen oxides (NOx)\, reactive organic gases (ROG)\, and diesel particulate matter (PM). Off-road has surpassed on-road vehicles as the largest source of statewide NOx emissions in 2017. As the regulations for off-road equipment tend to follow those for on-road vehicles by a few years\, the relative contribution of emissions from off-road equipment is expected to continue to grow\, absent additional controls. \nBiography: Dr. Liu received her bachelor’s degrees in environmental science and Economics from Peking University in Beijing. She went on to receive her master’s and Ph.D. in Environmental Engineering from the University of Illinois. Her Ph.D. work focuses on air emissions from mobile sources and the overall health and climate impacts from freight transportation. Dr. Liu currently works for the California Air Resources Board (CARB) in the Mobile Source Branch\, specifically in the Off-Road Diesel Analysis Section. Her work mainly includes development of off-road emission inventories and rule measures to support CARB’s air quality\, public health\, and climate goals.

SUMMARY:EWC Seminar by Kofi Christie (Princeton): Membrane distillation for high salinity brine management: Scaling and energy efficiency
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nVirtual seminar: https://ncsu.zoom.us/j/96075468552?pwd=RlZvb2x2YmM3c25KQWdRaXNEdVhUUT09 \nAbstract: Membrane distillation (MD)\, a hybrid thermal-membrane desalination technology\, has recently received tremendous interest as a sustainable technology for the treatment of hypersaline brines. MD is tolerant to higher salinity than reverse osmosis (RO) and capable of leveraging low-grade thermal energy such as waste heat and geothermal energy. However\, several fundamental aspects need to be addressed to achieve resilient MD systems for industrial applications. In this seminar\, I will present and discuss two of such aspects from the perspectives of process optimization. First MD performance is constrained by inorganic fouling from mineral growth\, or scaling\, due to the increased concentration over time of sparingly-soluble feed water constituents. Accordingly\, careful control of the driving force for feed water concentration (i.e.\, the vapor pressure gradient across the hydrophobic membrane) has been used to improve the robustness of MD performance. Recently we discovered that an equivalent trans-membrane vapor flux (i.e.\, the rate of vapor transferred through the membrane per unit area) can be achieved at varying feed water temperatures by separately controlling the vapor pressure on the opposite side of the membrane. Such control has enabled the investigation of the thermodynamic state of the nucleating minerals at the interface between the feed water and the membrane. Second\, MD is highly competitive to RO when lowgrade thermal energy is applied efficiently. I will present findings that elucidate the nuanced variations in energy efficiency definitions when varying heat sources and operational configurations are applied. Our work highlights the importance of determining whether the integration of low-grade thermal energy will minimize the costly high-grade energy to maintain the process or maximize the usage of the greatest amount of latent heat upon feed recycling. At the conclusion of the seminar\, I will also discuss the prospects and research needs associated with MD to improve environmental sustainability at the water-energy nexus. \nBiography: Dr. Kofi Christie is a postdoctoral research associate in the Andlinger Center for Energy and the Environment as well as the Department of Civil and Environmental Engineering at Princeton University. Dr. Christie grew up in Atlanta\, GA and received his B.S. degree from Morehouse College in 2014\, and his M.S. and Ph.D. from Vanderbilt University in 2016 and 2020\, respectively. He worked with Prof. Shihong Lin for his doctoral dissertation\, where he sought to advance water treatment and desalination technologies for high-salinity wastewater. His thesis focused on expanding our understanding of membrane distillation through module-scale thermodynamic analysis and elucidation of the causes and effects of inorganic fouling on membrane surfaces. At Princeton University\, Dr. Christie is working in the WET (Water & Energy Technologies) Lab of Prof. Z. Jason Ren. Dr. Christie’s work explores the intersection of membrane separation and crystal nucleation to sustainably recover solid and liquid resources from wastewater streams associated with coal-fired power plants. Additionally\, Dr. Christie works under the mentorship of Rodney Priestley\, Pomeroy and Betty Perry Smith Professor of Chemical and Biological Engineering. He is the recipient of several academic and professional awards\, including the National Science Foundation (NSF) Innovation Corps Grant (2020)\, the Princeton Presidential Postdoctoral Fellowship (2020)\, the NSF Graduate Research Fellowship (2015)\, and the IBM-Vanderbilt Graduate Fellowship (2014).

SUMMARY:EWC Seminar by Erin McDuffie (virtual); Environmental Science at the Interface of Policy: Sources of Air Pollution\, Public Health Impacts\, and Lessons Learned from a Year in D.C.
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nVirtual seminar link: https://ncsu.zoom.us/j/96075468552?pwd=RlZvb2x2YmM3c25KQWdRaXNEdVhUUT09 \nAbstract: Long-term exposure to outdoor fine particulate matter (PM2.5) is attributable to over 4 million deaths each year. Understanding the sources of PM2.5 pollution in a given location can help to inform the development of effective air pollution control policies. Leveraging recent advances in air quality modeling\, emission inventories\, remote sensing\, and public health data\, our interdisciplinary team conducted a comprehensive assessment of air pollution sources and the attributable disease burden across over 200 countries and sub-national regions. Our study approach provides results with consistent coverage across each country\, and for the first time\, also quantifies the global health impact of multiple individual fuel types\, including coal and solid biomass. Results reveal that dominant sources of PM2.5 vary both between and within each country and identify multiple options for improving air quality in the most polluted regions. Fossil fuels alone contribute to 27% (1 million deaths) of the total global PM2.5 disease burden. Combined with the PM2.5 pollution from residential biomass combustion\, results suggest substantial public health benefits from replacing traditional energy sources. In this presentation\, I will first focus on the study methods\, the main results\, and their policy relevance.

SUMMARY:EWC Seminar by Gabriel Isaacman-VanWertz (Virginia Tech): A little goes a long way – the outsize influence of small chemical differences in a complex atmosphere
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nIn-person: Fitts-Woolard Hall 2331 \nVirtual seminar link: https://ncsu.zoom.us/j/92010077484?pwd=aFlOQmp5dHVKMmNnK0w0Qi9hREJWdz09 \nAbstract: Reactive organic carbon is emitted to the atmosphere as a relatively small number of molecules and compound classes\, which undergo sunlight-drive oxidation processes to form a dynamic and complex mixture of thousands of compounds. The physical and chemical transformations of each organic compound is dictated by physicochemical properties that depend critically on the molecular structure of the molecule. However\, little work has examined the prevalence of compounds that differ only in their molecular structure (i.e.\, isomers)\, or the extent to which ignoring structure degrades understanding of the sources\, transformations\, and fates of organic compounds in the atmosphere. This presentation will examine the prevalence of isomers in the atmosphere\, where they come from\, and the extent to which knowing their structures matters in understanding the atmosphere. Observations of biogenic organic carbon in central Virginia will be presented\, with a focus on the dominant and variable role of isomers that are low in abundance by high in reactivity. The prevalence of isomers formed in the oxidation of these compounds will then be examined using a combination of novel instrumentation and chemical modeling. Finally\, the physicochemical properties of isomers in these oxidation product mixtures will be compared to quantitatively understand differences in their atmospheric transformations. Together these approaches will provide insight into the role of structure in the competition between different atmospheric processes\, and the consequent fate of a molecule. \nBiography: Gabriel Isaacman-VanWertz is an Assistant Professor in the Department of Civil and Environmental Engineering at Virginia Tech. He completed\nhis PhD at the University of California\, Berkeley\, after which he spent two years as an NSF Postdoctoral Fellow at MIT. He is originally from the East Coast\, growing up in Maryland and completing his undergraduate at Wesleyan University in Connecticut. He currently lives in Blacksburg\, VA with his wife and two young kids\, where he spends his free time trying to keep the deer and groundhogs from eating everything in their garden.

SUMMARY:EWC Seminar by Lauren Lowman (Wake Forest University): Uncovering the effects of extreme events on carbon\, energy and water budgets
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nIn-person: Fitts-Woolard Hall 2331 \nVirtual seminar link: https://ncsu.zoom.us/j/92010077484?pwd=aFlOQmp5dHVKMmNnK0w0Qi9hREJWdz09 \nAbstract: Extreme weather events are costly\, deadly\, uproot people from their homes\, and can have devastating effects on human life\, health and the economy. They are also a natural part of variability in our climate and play a role in maintaining healthy ecosystems. The purpose of this talk is to quantify the impact of extreme events on regional carbon\, energy and water budgets. Using high-resolution land-surface hydrology models\, plant hydraulics models\, and predictive phenology models\, we simulate how vegetation canopies respond to changes in atmospheric and soil conditions as a result of extreme events. Specific applications of the coupled hydrology-phenology modeling framework include understanding the sensitivity of montane cloud forests to changes in microclimate\, assessing the role that vegetation water use strategies play in the evolution of flash drought events\, and quantifying the impacts of wildfires in humid climates on the carbon and energy budgets. A key finding is that the magnitude of the change in the carbon cycle as a result of these extreme events are similar\, while the governing processes may be vastly different. This work highlights the need to understand how vegetation processes modulate carbon\, energy\, and water fluxes towards the goal of managing and maintaining healthy ecosystems. \nBiography: Lauren Lowman is an Assistant Professor in the Engineering Department at Wake Forest University and has served in this role since 2018. She received a Ph.D. and M.S. in Civil and Environmental Engineering with a focus in Hydrology and Fluid Dynamics from Duke University\, and a B.A. in Public Policy Studies from Duke University. Her research investigates how extreme events affect overall ecosystem health\, productivity\, and sustainability using numerical models\, geospatial data analysis\, and field experiments. She is passionate about developing and sharing inclusive teaching practices in STEM fields and received a 2020 Engineering Unleashed Fellowship from the Kern Family Foundation to support this work (hiddenSTEMwfu.edu | @hiddenSTEMfigs on Twitter & Instagram).

SUMMARY:EWC Seminar by Sherri Cook (University of Colorado Boulder): Integrating Sustainability and Resilience to Support Sustained and Universal Sanitation Access
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nVirtual seminar link: https://ncsu.zoom.us/j/92010077484?pwd=aFlOQmp5dHVKMmNnK0w0Qi9hREJWdz09 \nAbstract:\nSanitation systems fail globally at high rates. Researchers and practitioners attribute causes of sanitation success and failure to numerous factors that include both technical and non-technical issues. A comprehensive understanding of what leads to sanitation failure\, and how to achieve sanitation success\, is imperative to prioritize the use of limited resources. To this end\, first\, I will discuss how sanitation sustainability is currently measured and identify improvements to current approaches. Next\, I will discuss a new approach created by my research group that harmonizes current efforts and better supports context-specific sustainability assessments. This will include opportunities for improving measurements of environmental and human well-being\nassociated with sanitation access and quality. Finally\, a case study of sanitation systems in a hazard-prone area will be evaluated to improve the understanding of the understudied area of sanitation resilience. The overarching goal of this set of works is to progress towards sustained global sanitation coverage and access that is both sustainable and resilient. \nBiography: Dr. Sherri Cook is an Assistant Professor of Environmental Engineering at the University of Colorado Boulder. She received her M.S. and Ph.D. in Environmental Engineering from the University of Michigan\, and her B.S. in Civil Engineering from Virginia Tech. Dr. Cook’s research and teaching interests include the design and implementation of sustainable and resilient water\, sanitation\, and civil systems. Her research group is currently investigating biological treatment technologies for water reuse\, recovering resources (such as energy and nutrients) from organic solid wastes\, and developing sustainability frameworks to identify the most appropriate implementations of existing technologies and to set sustainability targets for technology development\, especially for PFAS water remediation and water reuse treatment technologies.

SUMMARY:EWC Seminar by David Farnham: Climate-related risks and opportunities for 21st century energy systems.
DESCRIPTION:Environmental\, Water Resources\, and Coastal Engineering Seminar Series \nVirtual seminar link: https://ncsu.zoom.us/j/92010077484?pwd=aFlOQmp5dHVKMmNnK0w0Qi9hREJWdz09 \nAbstract: Weather and climate conditions impact energy infrastructure operations in numerous and critical ways. For example\, heating and cooling energy demands are dependent on temperatures\, and the productivity of wind and solar generation farms are subject to surface wind and cloud cover conditions. Transitioning to a low-carbon energy system\nand relying more on wind and solar power generation is likely to increase our energy system’s dependence on weather conditions. This potential increased exposure to variable weather conditions presents a new set of challenges and opportunities for energy system planners and operators to design adaptive\, reliable\, and resilient systems. In this talk I will highlight work that quantifies weather- and climate-related risks and opportunities for an evolving energy system. I will also present a statistical modeling tool for grid planning to understand the risks of undersupply in wind and solar generation scenarios and an applied modeling effort to provide a rough estimate of the economic cost effectiveness of a globally interconnected wind and solar powered electricity grid. \nBiography: David Farnham combines earth science\, data science\, and systems analysis to (1) identify vulnerabilities of our water and energy infrastructure to climate variability and climate change\, (2) quantify climate hazards to these critical infrastructure systems\, and (3) conduct research that supports efforts to design and operate adaptive and resilient\nengineered water and energy systems that limit exposure to climate risks and make use of the opportunities presented by nature. David is a postdoctoral research fellow at Carnegie Science and the Department of Global Ecology at Stanford University working with Dr. Ken Caldeira. David is an engineer and applied scientist who investigates climate risk to critical water and energy infrastructure. David holds a PhD from the Department of Earth and Environmental Engineering at Columbia University where he studied under the advisement of Dr. Upmanu Lall.
