As a researcher and practice engineer, I have worked on several projects some of which summarized below.

Projects

Project 1. Impacts of Climate Stressors on Environment and Public Health (Funding Agency: Through Environmental Institute at Jackson State University, National Institute of Health (NIH); PI: Dr. Himangshu Das, Jackson State University)

  • Reviewed Federal Emergency Management Agency (FEMA) flood models for rain depth versus flood response for coastal Mississippi counties. Developed a statistical model to explore the risks and sensitivities of coastal Mississippi’s critical infrastructure, environment and public health due to flooding under current and future climate change scenarios.

Project 2. Enhanced Stormwater Treatment at Scrap Metal Facilities (Funding Agency:   Institute of Scrap Recycling Industries, Inc. ISRI; PI: Dr. Robert Pitt, University of Alabama).

  • Lead research efforts of a research study unit of multi-institutional and multi study units project to characterize scrap metal industrial runoff pollution and evaluate performance of effluent treatment units for controlling sediments and heavy metals.

Project 3. Associations of Polycyclic Aromatic Hydrocarbons (PAHs) with Urban Creek Sediments, (Funding Support: National Science Foundation (NSF); Research Advisor: Dr. Robert Pitt)

  • Developed a laboratory technique that coupled thermal desorption to Gas Chromatography/Mass Spectrophotometry for rapid analysis of semi-volatile toxicants. Studied influence of pollution source area land uses on partitioning fates of PAHs. Developed pollutant fate model based on fugacity concept to verify field observed partitioning fates of PAHs in the environment and examined possible impact of selected environmental factors on pollutant portioning.

Project 4. Lake Arlington Master Plan Development, Arlington, TX (Funding Support: City of Arlington)

  • Developed Geographical Interface System (GIS) enabled PLOAD model (a pollutant loading model) to simulate watershed hydrology and non-point source pollution. Land use GIS data, watershed boundary data along with Digital Elevation Model (DEM) data was processed to establish the watershed model to simulate nutrients, sediments and E.Coli pollution in the watershed. Developed a detail BATHTUB – an empirical model for lake and reservoir eutrophication- to investigate watershed management strategies.

Project 5. Medina River Holistic Watershed Master Planning (Funding Source: San Antonio River Authority, San Antonio, TX)

  • Developed calibrated hydrodynamic surface runoff and receiving water hydrology-water quality model using HSPF model to simulate 1,100 square miles, including a reservoir, for five continuous years at 5 minute intervals to investigate watershed water balance, nutrients and bacterial fate and transport.

Project 6. Water Pollution Sources and Transport Modeling (Funding Support: City of Birmingham, AL)

  • Investigated impacts of urban development on local flooding, water infrastructure and receiving water quality. Research focused project tasks included continuous simulation of 100 square mile Village Creek watershed, spanning across several municipalities, using EPA Stomrwater Management Model (SWMM). Pollutants of study focus were heavy metals, E. Coli and Sediments.

Project 7. Black Warrior Pollutant Transport Modeling (Funding Support: Birmingham Water Works Board, AL)

  • Three dimensional Environmental Fluid Dynamic Code (EFDC) based river simulation model was developed to investigate fate and transport of metals and sediments in about 2.5 mile stretch of Black Warrior River in Walker County, AL.

Project 8. Big Bear Lake Watershed TMDL Modeling (Funding Source: City of San Bernardino and San Bernardino County, CA)

  • Updated hydrodynamic watershed hydrology and water quality models to assess Total Maximum Daily Load (TMDL) compliance. Surface watershed loading Hydrology Simulation Program – Fortran (HSPF) model was coupled to receiving water pollutant fate and transport Water Quality Analysis Simulation Program (WASP) model for the watershed simulation.
