EXPERTISE

GSI applies runoff and floodplain models to solve hydrologic problems; performs non-point source pollution studies; and provides services related to in-stream and estuarine quality.

REPRESENTATIVE EXPERIENCE

Non-Point Source Studies: Developed innovative calculation methodology and determined non-point source loadings (stormwater pollutant loads) to the Galveston Bay estuary using LANDSAT satellite imagery for delineating land use.

Estuary Studies: Served as Principal Investigator for Galveston Bay Characterization Report for U.S. EPA's and State of Texas Galveston Bay National Estuary Program; analyzed wetlands, physical processes, water/sediment quality, and living resources of the Bay.

Surface Water Planning: Served as Principal Investigator for developing The Galveston Bay Plan, a comprehensive planning document for managing aquatic and living resources in Galveston Bay.

Floodplain Models: Conducted detailed floodplain management study of lower San Jacinto River watershed using HEC-1 and HEC-2 models.

Non-Point Source Monitoring: Managed all phases of $1.2 million EPA water quality/hydrologic monitoring system for EPA's Nationwide Urban Runoff Program in Kansas City. Designed and directed installation of twenty automatic sampling stations and monitored 23 storm events.

Oil Field Studies: Evaluated impact of oil field brine groundwater discharge on surface water resources. Analyzed flow data, dilution factors, and developed target concentrations for protecting livestock.
