Designed and conducted multiple aquifer tests to identify anisotropy within a wide oxbow stretch along the Mississippi River in St Louis, Missouri.  Developed an integrated surface-groundwater model and validated the same to historically observed (terrestrial and subsurface) hydrologic conditions.  Model utilized to design a multi-use transportation network along the Mississippi River.

Developed a multilayer model of the surficial and Floridan aquifer systems in Flagler County, Florida. Model used by the District for conducting vegetation harm analysis and determining optimal sites and pumping rates for new well fields so as to minimize environmental impacts on wetlands.

Developed mathematical algorithm for estimating sewer pipe network construction costs utilizing site environmental, geologic, and climatic data, along with economic statistics such as regional labor costs and consumer price index trends. Developed a graphical user interface to assist the user in bidding on construction projects using the pricing scheme developed for the project.

Developed an integrated MODFLOW-CROPSIM soil-groundwater stream-aquifer interaction model covering the Lower Platte basin in eastern Nebraska. The model is utilized by the Nebraska Department of Natural Resources to conduct stream depletion analysis for groundwater permitting and management purposes. The model domain covers seventy four watershed basins and accounts for transient evaporation, precipitation, runoff, plant uptake, and irrigation to derive aquifer recharge. Aquifer parameterization was accomplished using the Pilot Point methodology, and the coupled model calibrated with the PEST optimization software.

Developed a mutli-layer hydrologic model for determining safe wellfield yield in close proximity to waste management sites from which volatile organic compounds and metals were leaching in the subsurface. The objective of the study was to establish pumpage patterns that minimize contaminant movement and maintain water quality standards mandated by EPA’s Safe Drinking Water Act.

Consultant for Lower East Coast saltwater intrusion modeling initiative undertaken by South Florida Water Management District. Developed model conceptualization and implementation plan for project. Examined the role of temperatures in the coastal flow dynamics along the southern tip of the Floridan peninsula.

Developed software package to assist in automated design of low pressure sewer networks operated by grinder pumps. Algorithm accounts for variable terrain, utilizes statistics for inferring usage patterns, and is based on retention time analysis to minimize sulfide generation in pipe networks.

Simulated flow emanating at the surface and traversing through the vadose zone in a highly heterogeneous groundwater reservoir at a contamination site in western United States. The model was utilized to identify parties responsible for hydrocarbon contamination in the area.

Developed mathematical procedures and methodologies for estimating well field pumpage utilizing pumped water quality data. Solved the highly nonconvex optimization problem within a global framework. Utilizing the software, pumpage in each wells can be determined by simply using water quality data in a well and knowing the cumulative wellfield pumpage.

Constructed groundwater model of drift-filled pre-glacial valley in northwest Missouri. Model utilized to determine the extent and lithologic framework of the relatively narrow buried channel, identify optimal locations for a proposed wellfield, and to determine aquifer safe yield for a 20-year time horizon.
