SUMMARY:Energy Systems Modeling with High Performance Computing Resources: Joe DeCarolis
DESCRIPTION:Climate change coupled with rapid technological innovation is driving large scale change in the global energy system. Computer models of the energy system – referred to as energy optimization system models – provide a way to examine future energy system evolution\, test the effects of proposed policy\, and explore the role of future uncertainty. Modeling the whole energy system is computationally intensive and requires large input datasets. In addition\, in order to deliver insights that are robust to large future uncertainties\, it is necessary to iterate the model many times under different scenario assumptions. \nIn this talk\, Dr. Joseph DeCarolis\, Professor in the Department of Construction\, Civil\, & Environmental Engineering at NC State\, will highlight ongoing work using Tools for Energy Model Optimization and Analysis (Temoa)\, an open source energy system optimization model developed at NC State that is designed to conduct rigorous uncertainty analysis and make use of high-performance computing resources. \nThe Research Computing series is a forum for information sharing about high-performance computing\, deep learning\, parallel computing\, and other relevant topics. This talk is being offered in conjunction with Energy Week. \nTo register for this event click here. Registrants will receive a zoom link prior to the event.

SUMMARY:C & S Colloquium: Dr. Sankar Arumugam
DESCRIPTION:Title: Design and Adaptation under a changing world – Opportunities for Synthesis and Convergence Research\n\nAbstract: One of the critical concerns in using climate change projections for design and adaptation is in the uncertainty and variability in the projections depending on the emission scenarios.  It has been shown that this uncertainty in the projections  is at its minimum  over the near-term (10-30 years)\, which is a critical time scale for infrastructure planning. In this sabbatical talk\, I present a methodology for revising USGS flood frequency analysis – a federally mandated procedure for designing spillways and bridges – using near-term climate change projections. Working with the USGS scientists on a federal highway project also highlighted how flood information is viewed and interpreted across disciplines\, thereby necessitating the need for synthesis for flood frequency analyses under various thresholds of change.  Such synthesis also needs to promote a convergence approach on quantifying the potential flood risk from the societal perspective. Towards this\, I will present potential opportunities for convergence research within NSF and other agencies and  will also discuss ongoing initiatives on urban flooding from the NSF funded convergence accelerator (C-ACCEL) project.\n\nBio: Dr. Sankar Arumugam is a Professor and University Faculty Scholar in the Department of Civil\, Construction\, and Environmental engineering at NCSU. Sankar spent the sabbatical at the USGS headquarters in Reston (VA) and also at the USGS John Wesley Powell Center for Synthesis and Analyses at Fort Collins (CO).  He also collaborated with the UCAR scientists on performing a review of methodologies on sub-seasonal to seasonal streamflow forecasting at Boulder\, CO.

SUMMARY:CE 2050 Faculty Seminar: Dr. Abhinav Gupta
DESCRIPTION:Title: Role of Civil Engineering in improving sustainability\, resiliency\, and growth of nuclear energy\n\n\nAbstract: Civil Engineers play a significant role in the sustainability and safety of existing nuclear power plants as well as in the design and construction of advanced reactors. Structural safety assessments are key to ensuring resiliency of not only the concrete containment and other buildings but also the mechanical and electrical systems. Engineers continue to work on improving the resiliency of these large complex systems against natural hazards such as earthquakes\, hurricanes\, and floods. In addition\, the plant systems exhibit fairly significant thermal and vibration fatigue\, flow assisted corrosion\, and ageing related degradation during their lifetimes. All of these aspects require innovative solutions based on the concepts of structural mechanics\, innovative materials\, geotechnical engineering\, fluid-structure interactions\, computational fluid dynamics\, non-destructive testing\, health monitoring\, etc. In recent decades\, nuclear industry has led the development of risk-informed design and decision making approaches for operational as well as licensing decisions. This requires appropriate characterization of uncertainties in our understanding of physical phenomenon and in our models that are used to represent them. Some of the most recent research has focused on developing risk-informed methodologies for verification and validation of advanced simulation tools and on developing Artificial Intelligence (AI) based solutions to assist with the design and construction of advanced reactors which are truly being designed as cyber-physical systems. Nuclear industry has also struggled with managing the cost and schedules of constructing new large-sized plants throughout the developed countries. Recent research aims to address this aspect through an integrated virtual design and construction platform that uses the power of digital and thermal imaging. Presently\, more than a quarter of North Carolina’s electricity comes from nuclear and at national level this largest source of carbon-free electricity generation contributes about 20% to our consumption.

SUMMARY:C&S Colloquium: Amir Mazrooei and Sudharshana Mukhopadhy
DESCRIPTION:Dr. Amir Mazrooei (post-doctoral associate\, CCEE) and Ms. Sudharshana Mukhopadhy (PhD Candidate\, CCEE) will discuss software tools developed by CCEE for hydroclimatological geospatial analyses.  Refreshments will be provided. Details follow. \n  \nGeospatial Analyses using GrassGIS: A Global Assessment Of ET fluxes Impacted By Anthropogenic Land Cover Changes \nDr. Amir Mazrooei   \nGrass GIS is a fully functional software that can handle many different geo-spatial analyses tasks such as vector processing\, image and raster analyses\, and database creation. Unlike ESRI’s ArcGIS\, Grass is open source and can be compiled and executed in Linux environments which makes it much easier in terms of bash scripting\, and much faster to conduct large-scale analyses. In this C&S seminar\, as part of my ongoing research about the human influence on natural hydroclimatic conditions\, I would present how urbanization affects evapotranspiration (ET) flux rates in a global scale\, resulting in urban heat islands. We would see a demo of the quantitative analysis of remotely sensed data through Grass GIS\, along with the post-processing and visualization of the results using R. \nA geo-processing tool for co-locating the dependency of critical infrastructure with hydrologic information network \nMs. Sudharshana Mukhopadhy  \n \nUnderstanding the interactions between the natural environment and physical infrastructure is critical for sustainable development. Most water infrastructure such as reservoirs\, dykes\, wastewater treatment plants depend on river conditions and other infrastructure (e.g.\, power system)\, but the nature of the river network introduce a cascading interdependency between the regional riverine system and their infrastructure. We have begun to address this by developing an R package\, River-Infrastructure Cascade (RIC) and demonstrating it for referencing the reservoirs with respect to streamgage network over the entire Coterminous United States (CONUS). I will discuss our systematic approach of combining multiple layers of topographic information of infrastructures with high resolution National Hydrographic Dataset (NHDPlusv2) over the Colorado River Basin (CRB)\, and I will illustrate our methods of handling different conditions along the river network – such as river junctions (e.g. divergences\, convergences or both)\, boundary of watershed\, isolated network and coastlines or end of a stream reach.

SUMMARY:Kappe Lecture 09/27 : Dr. Nancy Love
DESCRIPTION:Our EWC seminar on this Fri Sep 27 will feature Dr. Nancy Love from the Univ of Michigan\, who will discuss: “Environmental Engineering and Science Academic Scholarship in Service to Society: Our Role and Responsibility.”  An abstract is included below.  This is a special seminar as part of the AAEES Kappe Lecture Series\, and so we will meet at a special time and place — please join us in Mann 307 from 3-4pm. \nTitle: Environmental Engineering and Science Academic Scholarship in Service to Society: Our Role and Responsibility \nSpeaker: Dr. Nancy Love\, University of Michigan \nAbstract: Academic scholarship in environmental engineering and science is most often associated with research around environmental science and technology – research that often involves physical or computational experiments – and sometimes occurs in nature or with full-scale engineered systems. Our discipline also has a growing contribution around the scholarship of learning and teaching\, which has driven pedagogical advancements to the betterment of students and the organizations that hire them. A third wave of scholarship in the environmental engineering and science discipline that is seeing rapid growth relates to community-engaged research\, learning and outreach. An increasing number of colleges are advocating that faculty and students do more work in service to society; in this way\, universities are helping to motivate the third wave. Community-engaged work takes various forms\, from research in partnership with communities\, service-learning oriented courses\, and professional outreach through institutions (e.g.\, civic organizations\, professional associations). Many faculty and students undertake this third kind of scholarship with good intentions; however\, they have typically received little to no training for it\, and few to no processes\, standards or certification methods are in place that explicitly focus on ensuring our work in communities is done in a manner that is respectful\, mutually beneficial and does no harm. During this talk\, I will review the history and status of standards\, ethics codes and other methods that are designed to protect the public while allowing for valid modes of public scholarship in service to society\, with an emphasis on environmental engineering and science academia. I will use case studies to highlight exemplary projects that met the community and academic goals in a mutually beneficial way. I will close with recommendations that highlight needs as our discipline more fully embraces scholarship in service to society.

SUMMARY:Henry Shaw Lecture: Dr. Alain L. Kornhauser
DESCRIPTION:SmartDrivingCars… Where have we been\, where are we\, and where are we going? \nDr. Alain L. Kornhauser\n\nProfessor\, Operations Research and Financial Engineering\nFaculty Chair\, Princeton Autonomous Vehicle Engineering \n\n\nThursday September 12th\nMann Hall Room 307 at 3:00pm\nReception to follow in Mann Hall Lobby\n\n\n\n\nAbstract: Mobility is closely correlated with quality-of-life; better mobility with better quality-of-life. It is not surprising that technologists for centuries have looked to improving mobility as the beneficiary for emerging physical/analog technologies. It is not surprising that digital technologist have focused on mobility as their opportunity to make a difference. With IVHS (Intelligent Vehicle Highways Systems\, 1991\, evolving into ITS in 1994)\, digital technology began improving mobility. What started as a largely public-sector initiative has emerged into an investment bubble that has committed over $100 Billion in the last 10 years from the private sector to the development of automated road vehicles\, or what I’ve termed SmartDrivingCars. The perceived opportunity is to fundamentally disrupt the $10Trillion/year mobility industry. The seminar will explore the visions that motivated the massive investment\, where we are today\, and the public policy implications of the range of realities that may emerge.\n\n\nBio: Alain Kornhauser is a Professor of Operations Research & Financial Engineering at Princeton University. He studied Aerospace Engineering at Penn State where he obtained a BS and MS and Princeton\, earning a PhD. In 1971 he joined the Aerospace Engineering faculty at U of Minnesota where he applied automation\, network analysis and optimal control to the design of Personal Rapid Transit (PRT) Systems.  He returned to Princeton in 1972\, to extend his pivotal work to more conventional forms of transportation and serve as Director of the Transportation Program.\n\n

An abstract and bio are included below; more information is available on his web site.  Please join us in Mann 307 from 4:30-5:30pm. \nTitle: New Approaches to Pipeline Condition Assessment Using Pressure Transients and Adventures in Smart Water Networks \nAbstract: Water distribution systems (WDSs) are important infrastructure assets however\, pipe networks in many countries are suffering widespread and significant structural deterioration due to ageing. The need to replace this aging infrastructure is becoming a critical issue for condition assessment managers. Due to the lack of information on pipeline condition\, pipe replacement programs are often replacing pipes that are in an acceptable condition and missing pipes that will inevitably burst. The deterioration introduces water loss through leaks\, increases the cost of operation and maintenance\, and sometimes results in disruptive events such as pipe bursts. Hydraulic transient pressure waves have the potential to be used as a tool for non-invasive assessment of water supply pipelines starting with a focus on leak detection then extended to pipe wall condition assessment. The development of the Smart Water Network (SWN) deployed in Adelaide CBD consists of 305 accelerometers\, 23 hydrophones loggers and 23 pressure loggers which have been installed permanently across the network to monitor its acoustic and hydraulic behaviour. Preliminary studies have demonstrated that the data obtained creates an opportunity for better understanding of the water distribution network\, better-informed asset management and provides an interesting contrast to the pipe condition assessment research. \nBio: Prof Martin Lambert was the Head of School the School of Civil\, Environmental and Mining Engineering at the University of Adelaide from 2015 to 2018 and was previously Head of the School from 2009-2012 and the Associate Dean (Research) in ECMS from 2006-2009. His research has focused on several aspects of water engineering related to the use of fluid transients for the effective and efficient condition assessment of the aging pipe infrastructure\, smart networks and stochastic hydrology. He has taught a range of subjects in the School and has been awarded several prizes for teaching including the University Prize for Excellence in Higher Degree by Research Supervision in 2008 and an Australian Learning & Teaching Council citation in 2009.

SUMMARY:C & S Colloquium: Jorge Pesantez
DESCRIPTION:A Multi-Phase Procedure to Design District Metered Areas for Water Distribution Networks \nJorge Pesantez\, PhD Candidate \nAbstract: Dividing a water distribution network into subsystems can improve the efficiency and ease of achieving management goals. Subsystems or District Metered Areas (DMAs) are isolated  control zones with a defined number of entrances and exits. This research presents an automatic approach based on graph theory\, optimization\, and a heuristic methodology to design DMAs for water systems by minimizing the coefficient of variation of demand similarity among DMAs. The Multi-Phase Procedure to Design DMAs (MPPDMA) satisfies constraints specified to limit the number of entrances per DMA\, meet maximum and minimum pressure at non-zero demand nodes\, and maintain water levels of the tanks over extended periods of simulation. MPPDMA is applied to four water networks. Results demonstrate that MPPDMA can improve demand similarity among DMAs.

SUMMARY:EWC Seminar 04/27 : Jeremiah Johnson
DESCRIPTION:Our EWC seminar on this Friday\, Apr 27\, will feature our own Dr. Jeremiah Johnson\, who will discuss: “Life Cycle Environmental Impacts of Lithium Ion Batteries when Used for Power Systems Reserves.”  An abstract and bio are included below.  Please join us in Mann 304 from 12:50-1:40pm. \nAbstract: Battery storage systems are attractive alternatives to conventional generators for frequency regulation\, due to their fast response time\, high cycle efficiency\, flexible scale\, and decreasing cost. However\, their implementation does not consistently reduce environmental impacts. In order to assess these impacts\, we employ a life cycle assessment (LCA) framework.  Our framework couples cradle-to-gate and end-of-life LCA data on lithium ion batteries with a unit commitment and dispatch model. The model is run on a 9-bus power system with energy storage used for frequency regulation.  The addition of energy storage changes generator commitment and dispatch causing changes in the quantities of each fuel type consumed. This results in increased environmental impacts in most scenarios. The impacts caused by the changes in the power system operation (i.e.\, use-phase impacts)\, outweigh upstream and end-of-life impacts in the majority of scenarios analyzed with the magnitude most influenced by electricity mix and fuel price. Of parameters specific to the battery\, round trip efficiency has the greatest effect. \nBio: Jeremiah Johnson is an associate professor at North Carolina State University’s Department of Civil\, Construction\, and Environmental Engineering and part of the Chancellor’s Faculty Excellence Program in Sustainable Energy Systems and Policy. His research uses systems methods to evaluate the environmental impacts of changes to the power system\, including those driven by technology (such as the integration of wind power\, solar photovoltaics\, and energy storage) and policy. Dr. Johnson teaches courses related to sustainable engineering\, life cycle assessment\, and energy systems analysis. He earned degrees in environmental engineering from Yale University (PhD\, MS) and in chemical engineering from Clarkson University (BS).  In addition to his time in academia\, Dr. Johnson spent several years as a management consultant advising electric utilities on renewable energy strategy and environmental compliance.

SUMMARY:EWC Seminar 04/20 : Celso Castro-Bolinaga
DESCRIPTION:Our EWC seminar on this Friday\, Apr 20\, will feature Dr. Celso Castro-Bolinaga from the NCSU Department of Biological & Agricultural Engineering.  He will discuss: “Dynamics of Fine-Grained Sediment Pulses in River Corridors: An Adaptive Numerical Simulation Approach.”  An abstract and bio are included below.  Please join us in Mann 304 from 12:50-1:40pm. \nAbstract: An adaptive numerical simulation approach to characterize the propagation of fine-grained sediment pulses in river corridors will be presented. The objective of this work was to identify the properties of these types of pulses and those of riverine environments that are more relevant to their downstream migration. Numerical tests were carried out to investigate the influence of the pulse grain size distribution and volume\, as well as the influence of the ambient discharge and channel slope\, on the dominant propagation mechanisms. Results indicate that the reconfiguration of the deposited material is governed by an initial dispersion-dominated phase during which there is a rapid movement of the pulse forefront\, followed by a subsequent phase characterized by a pronounced translational movement of the pulse apex. The dispersion phase is governed by suspended-load driven regimes that actively entrain material from the top part of the pulse\, carrying finer sediment further downstream while depositing coarser particles close to the original forefront location. During the translational phase\, on the other hand\, the velocity in the flow field surrounding the pulse topography decreases and the sediment transport regime is no longer controlled by suspended load\, but rather by a combination of this mode of transport near the pulse forefront and bedload transport across the pulse core region. The transition between these two phases is controlled by the value of the Froude number (Fr) over the pulse topography\, whereas their intensity and duration are dictated by the magnitude of the evaluated properties. Results suggest that the initial dispersive phase is characterized by high values of Fr (i.e.\, Fr ~ 0.7-0.9)\, whereas the translation component detected during the second phase is typically associated with more moderate values of Fr (i.e.\, Fr < 0.5). The numerical simulations indicated that\, independently of the parameter being tested\, the degree of translation is enhanced as the magnitude of Fr decreases\, and the transition between dispersion and translation occurs around a threshold value of Fr ~ 0.4-0.5. Moreover\, the influence of the evaluated parameters was observed to be relevant to the intensity and duration of each phase. \nBio: Dr. Celso Castro-Bolinaga is an Assistant Professor in the Department of Biological and Agricultural Engineering at NC State University\, where he leads the Fluvial Hydraulics and Sediment Dynamics Research Group. He received his Ph.D. and M.S. in Civil Engineering from Virginia Tech\, and completed his undergraduate studies in Civil Engineering at Universidad Católica Andrés Bello (UCAB) in Caracas\, Venezuela. Dr. Castro-Bolinaga’s research group focuses on studying processes that are governed by the dynamics of water and sediment in riverine environments. He and his team aim to provide a better understanding of how the spatial and temporal scales associated with such processes control hydro-geoenvironmental regimes in streams and rivers\, and ultimately the adaptation capacity of these natural systems to external drivers (e.g.\, climate and hydraulic works).

SUMMARY:Seminar: Integrated Computational Framework for Modeling Composite Materials with Intricate Microstructures
DESCRIPTION:Abstract \nSimulating the mechanical behavior of materials with complex microstructures has been a longstanding challenge in the field of computational mechanics. This presentation by Dr. Soheil Soghrati will introduce a new mesh generation algorithm\, named Conforming to Interface Structured Adaptive Mesh Refinement (CISAMR)\, for creating high fidelity finite element models of such problems. CISAMR transforms a simple structured grid into a high-quality conforming mesh with appropriate element aspect ratios and negligible discretization error using a non-iterative algorithm. Similar to eXtended FEM (XFEM)\, CISAMR preserves the original structure of the background grid after the construction of conforming elements. Moreover\, unlike conventional mesh generation algorithms such as Octree-based methods\, CISAMR does not need an iterative smoothing or relaxation process to improve element aspect ratios and thereby can easily handle complex morphologies. To fully automate the modeling process\, CISAMR is integrated with a novel microstructure reconstruction algorithm relying on statistical and geometrical information extracted from digital data such as microcomputed tomography (micro-CT) images. This algorithm not only can reconstruct microstructural models with realistic fiber/inclusion shapes but also can accurately synthesize the target volume fraction and spatial arrangement of heterogeneities. The current presentation demonstrates the application of this integrated computational framework for studying the multiscale failure response of a variety of composite materials subject to thermo-mechanical loadings\, including heterogonous structural adhesives\, carbon fiber reinforced polymers\, and cross-linked non-woven entangled fiberglass packs. \n \nSpeaker Bio \nDr. Soheil Soghrati is an assistant professor of Mechanical and Aerospace Engineering & Materials Science and Engineering at The Ohio State University (OSU). He earned his PhD in Structural Engineering with Minor in Computational Science in Engineering from University of Illinois at Urbana-Champaign and received his Masters and Bachelor degrees in Civil Engineering from Isfahan University of Technology. Dr. Soghrati joined the Department of Mechanical and Aerospace Engineering at OSU in June 2013 with a joint appointment in the Department of Materials Science and Engineering. He is also one of the steering board faculty members of the Simulation Innovation and Modeling Center (SIMCenter) at OSU. Dr. Soghrati’s research interests lay in the area of computational solid mechanics\, with special focus on the development and application of advanced numerical techniques for the automated modeling of problems with complex and/or evolving morphologies. Some of the ongoing research projects in his research group include simulating localized corrosion processes\, multiscale failure response of composite materials\, modeling non-woven entangled materials\, computational design of Lithium-ion battery electrodes\, and modeling sheet mold compounds.

SUMMARY:EWC Seminar 03/16 : Prakash Bhave
DESCRIPTION:Our EWC seminar on this Friday\, Mar 16\, will feature Dr. Prakash Bhave from ICIMOD.  He will discuss “Smogmandu: Sources\, Struggles\, Solutions\, and Progress in Nepal Air Quality.”  An abstract and bio are included below.  Please join us in Mann 304 from 12:50-1:40pm. \nAbstract: The World Health Organization estimates that 7 million people die prematurely every year due to inhalation of air pollutants\, and the vast majority of those deaths occur in developing countries.  In addition\, air pollution has a damaging effect on the sensitive mountain ecosystems of the Hindu Kush Himalaya region.  In recent years\, a variety of attempts have been made to understand ambient air quality in the region and identify practicable measures to manage it.  During this seminar\, Prakash will share several lessons he learned while living and working in Kathmandu from 2014 – 2017. He will summarize results from the Nepal Air Monitoring and Source Testing Experiment (NAMaSTE)\, report on the mitigation of emissions from brick kilns after the great earthquakes of 2015\, and describe how Nepali citizens were empowered to monitor their own air quality and subsequently raise public awareness throughout Kathmandu. He’ll also share some barriers encountered and the fixed mindsets that are inhibiting progress toward healthy air quality in the cities of Nepal and India. \nBio:  Dr. Bhave earned his Bachelor’s degree in environmental engineering science from the University of California at Berkeley and completed his Master’s and Ph.D. degrees at the California Institute of Technology (Caltech)\, specializing in computational modeling of atmospheric pollution with a focus on fine particulate matter.  He then worked at the U.S. Environmental Protection Agency (EPA) in RTP for 11 years\, where he developed the particulate components of the Community Multiscale Air Quality model which was used to support various national-scale regulations of coal-fired power plants\, motor-vehicle exhaust\, and automotive fuel standards. He served as an Assistant Laboratory Director in the EPA’s National Exposure Research Laboratory and as the Senior Science Advisor for EPA’s Atmospheric Modeling and Analysis Division. In 2013\, Prakash began feeling that his knowledge and work experience should be applied to a larger problem than the relatively modest levels of air pollution in the U.S. He conducted a worldwide search for jobs\, focusing on developing countries with hazardous air quality. He and his wife sold their home in Morrisville and left their jobs\, moving with their 3 young children to Kathmandu\, Nepal for a 3-year period.  Since returning to the Triangle\, Prakash enjoys sharing his overseas experiences and lessons learned with a variety of U.S.-based audiences.

SUMMARY:Joint CCEE & MEAS Seminar: Christophe Darnault\, Clemson University
DESCRIPTION:Flow and Transport in Porous Media: Applications in Environment and Energy \n \nDR. CHRISTOPHE DARNAULT \nAssistant Professor\, Department of Environmental\nEngineering and Earth Sciences\, Clemson University\nAssociate Editor\, Journal of Hydrology \nABSTRACT\nFlow and transport in porous media with applications in environment and energy are complex phenomena that encompass a\nwide range of disciplines\, including physics\, chemistry\, biology\, earth sciences\, hydrology\, soil and water engineering\, and \nreservoir engineering. Understanding flow and contaminants transport processes in porous media is critical for the mitigation\nof their impacts\, the development of effective remediation procedures\, the exploitation and management of subsurface\nresources — aquifer systems and petroleum reservoirs\, and the protection of the environment and public health. The release of\nemerging contaminants\, such as engineered nanomaterials\, into the environment; the prevalence of microbial pathogens due\nto wildlife and agricultural activities in rural and agricultural watersheds; and the discharge of radionuclide wastes during\nstorage\, handling\, and disposal of nuclear materials in groundwater systems are inevitable. To study the fate and transport of\nthese contaminants in the vadose zone\, we have investigated their mobility under different hydrodynamic and biogeochemical\nconditions found in the natural environment. We have demonstrated the critical role that preferential flow (macropore flow\nand fingered flow); transient in water content and velocity; transient in solution chemistry\, gas-water interfaces; solid\ninterfaces; system heterogeneities; plants and microbes; and their interactions and feedback have in the flow\, transport\, and\nretention of contaminants in the vadose zone. Mobilization of crude oil from geologic formations is essential for the\nexploitation of petroleum reservoirs and the oil recovery process. We have explored the ability of nanoparticles to improve the\nefficiency of the chemical-enhanced oil recovery process (EOR) that uses surfactant flooding by examining interfacial and\nrheological properties of multiphase systems and sandstone-crude oil-nanofluid systems. To elucidate the individual\ncontribution of the mechanisms and natural parameters affecting the flow phenomena\, transport\, and retention of these\ncontaminants\, as well as to quantify and visualize them\, we have developed monitoring methods and tools using physical\,\nchemical\, microbiological\, molecular\, and non-intrusive technologies. The results of our research will contribute to the\ndevelopment and validation of flow\, fate\, and transport models of contaminants from pore scale to watershed scale for\nmanagement and protection of groundwater resources\, petroleum reservoirs\, public health\, ecosystem sustainability\, risk\nassessment\, and life-cycle analysis. \nBIOGRAPHY\nChristophe Darnault is Assistant Professor at the Department of Environmental Engineering and Earth Sciences at Clemson\nUniversity.

SUMMARY:EWC Seminar 02/02 : Michael Breen
DESCRIPTION:Our EWC seminar on this Friday\, Feb 2\, will feature Dr. Michael Breen from the EPA.  He will discuss “Air Pollution Exposure Modeling for Epidemiology Studies and Public Health.”  An abstract and bio are included below.  Please join us in Mann 304 from 12:50-1:40pm. \nAbstract: Air pollution epidemiology studies of ambient fine particulate matter (PM2.5) often use outdoor concentrations as exposure surrogates. These surrogates can induce exposure error since they do not account for (1) time spent indoors with ambient PM2.5 levels attenuated from outdoor concentrations\, and (2) building-to-building and temporal variability of this attenuation. To help address the potential exposure error\, Dr. Breen is leading the development of individual-level air pollution exposure models\, integrated with novel personal sensor technologies\, to improve exposure assessments for epidemiology studies and for public health. He is co-investigator for multiple epidemiology studies assessing the exposure and health effects for participants with asthma\, diabetes\, and coronary artery disease. He is also the inventor of a new exposure smart phone App\, called TracMyAir. At this seminar\, he will present the development and application of these models to predict individual-level exposures for epidemiology studies\, in support of improving risk estimation. \nBio: Michael Breen is a research scientist in the National Exposure Research Laboratory at the EPA.  Dr. Breen’s current research focuses on the development of air pollution exposure models\, integrated with novel personal sensor technologies\, to improve exposure and risk assessments for individuals in health studies and citizen scientists. He is a co-investigator for multiple health studies assessing the exposure and effects of air pollutants. These health studies include participants with asthma\, diabetes\, and coronary artery disease living in various U.S cities. He has developed\, evaluated\, and applied novel exposure modeling and time-activity tools\, which includes the Exposure Model for Individuals (EMI) and GPS-based Microenvironment Tracker (MicroTrac) model.

SUMMARY:COPRI & EWC Seminar 01/23 : Ivy Huang
DESCRIPTION:Our seminar will be moved to a special day and time.  The NCSU student chapter of the Coasts\, Oceans\, Ports & Rivers Institute (COPRI) and EWC will co-host a seminar on Tuesday\, Jan 23\, in Mann 323 from 4:30-5:30pm.  The seminar will feature Dr. Ivy Huang\, who will discuss “Cohesive sediment flocculation in a partially-stratified estuary.” An abstract and bio are included below.  Please join us Tue Jan 23 in Mann 323 from 4:30-5:30pm. \nAbstract: Cohesive sediments play a key role in estuarine systems by 1) acting as carriers for contaminant transport; 2) affecting primary productivity through turbidity effects on in-water light levels; and 3) causing siltation in navigation channels. A major challenge towards studying cohesive sediments is the dynamic process of flocculation. This research is focused on developing a process-based understanding of cohesive sediment flocculation under various non-hydrodynamics and hydrodynamics conditions in the San Francisco Bay-Delta estuary. More specifically\, we investigated these processes using high-resolution transect and stationary measurements of stratified turbulence and floc properties. We make the following main observations. First\, we show that the floc size is not significantly affected by changes in salinity\, sediment concentration\, or biological activity. Comparison between the freshwater and saltwater flocculation dynamics shows that the traditional notion of enhanced floc aggregation at the onset of salinity is not appropriate in this estuary. Instead\, we conclude that the physical processes are the most dominant control on floc size. In particular\, we show that the floc sizes scale inversely with the strength of the turbulent shear rate (G). Over tidal timescales\, the smallest floc sizes are typically observed during slack water\, and the largest floc sizes are typically observed at peak current velocities. We also show that other physical processes\, such as differential settling\, are important and cannot be ignored. These secondary effects are most evident during the tidal transitions\, coinciding with when stratification is at its strongest. \nBio: Dr. Ivy Huang received her S.B. from MIT in 2011 and Ph.D. from Stanford University in 2017 (both in Civil and Environmental Engineering). Currently\, Dr. Huang is a California Sea Grant post-doctoral scholar working with Dr. Stephen Monismith and Dr. David Schoellhamer on understanding the effect of drought on sediment dynamics in freshwater systems. In particular\, she has had extensive experience leading and analyzing field and laboratory experiments on complex fluid-sediment processes and their impact on water quality.  Dr. Huang’s specific research interests include stratified turbulence\, sediment flocculation\, salinity fronts\, turbidity maxima\, and light availability.

SUMMARY:EWC Seminar 01/19 : Dario Del Giudice
DESCRIPTION:Our EWC seminar on this Friday\, Jan 19\, will feature our own Dr. Dario Del Giudice.  He will discuss “Improving estimation and predictions in hydrology and water quality.”  An abstract and bio are included below.  Please join us in Mann 304 from 12:50-1:40pm. \nTitle:\nImproving estimation and predictions in hydrology and water quality \nAbstract:\nClimatic variability combined with anthropogenic pressures can impact the hydrological cycle by triggering critical phenomena such as flooding and eutrophication. Mechanistic and statistical models can be powerful tools to understand and predict how aquatic systems respond to variability in climatic inputs such as precipitation. However\, in order to be useful\, models need to be appropriately formulated\, calibrated and validated.\nIn this talk we will explore different freshwater issues were choosing the appropriate type of model and uncertainty quantification method is paramount. Along the way\, we will deal with estimating the catchment-averaged precipitation with a limited gauging network\, predicting urban peak discharge in presence of high model bias\, and identifying the hydrometeorological factors controlling lacustrine oxygen depletion. We will go through different methodological approaches to perform calibration and predictions for aquatic systems at multiple spatial and temporal scales. We will see how at times sophisticated combinations of Markov processes and mechanistic models are required\, whereas in other cases simple methods such as least squares and linear regression can suffice. \nBiography:\nDario recently started his postdoctoral research at NCSU\, after moving from Stanford where he was working at the Carnegie Institution for Science. He is interested in the impact of climate variability and human pressures on the quantity and quality of water resources. In his research at the interface of catchment hydrology and surface water pollution he combines process-based models\, stochastic methods for uncertainty quantification\, and statistical inference. Dario is currently focusing on the complex issue of nutrients leaching from agricultural watersheds into surface waters and fostering eutrophication and oxygen depletion. Dario holds a PhD degree from the Swiss Federal Institute of Technology in Zurich\, a MSc from the École polytechnique fédérale de Lausanne\, and a BSc from the University of Bologna.

SUMMARY:C & S Colloquium: Kumar Mahinthakumar
DESCRIPTION:Sabbatical Experience at the University of Cape Town – Water distribution leakage detection and other research \n \nI will discuss my experience at the University of Cape Town (UCT) during my sabbatical from January to July 2017 as a US Fulbright scholar. In collaboration with the water distribution team at UCT\, previously developed methods at NCSU for leakage detection in water distribution systems were extended to include more realistic leakage models as well as model and data errors. The methods were validated for a district metering area in the city of Cape Town. I also worked with the urban water management group at UCT in examining groundwater pumping schemes for extracting infiltrated stormwater for a study area in Cape Town.
