Water Resources Management

HydroQual’s Water Resources Management practice focuses on the application of physics, chemistry, biology, and modern mathematical modeling to understand the fate and transport of contaminants in the natural environment and the effectiveness of management alternatives. HydroQual has applied one-, two-, and three-dimensional water quality models and processing tools, including visualization and animation routines, to problems associated with pathogens, nutrients, dissolved oxygen, organics and toxic chemicals. HydroQual’s mathematical modeling system framework is graphically presented here.

HydroQual also provides support services in the areas of Total Maximum Daily Load (TMDL) determinations, Waste Load Allocations (WLAs), Water Quality Based Effluent Limits (WQBELs), Use Attainability Analysis (UAA), guidance in the development of site-specific sediment and water quality criteria, wastewater facility planning, and the design of field monitoring efforts.

Our water quality modeling system code (RCA) has been applied on a large number of water bodies in the United States and throughout the world – a selected list of these projects is presented here (PDF). HydroQual engineers and scientists are also experienced in applying other public domain models developed and supported by the US Environmental Protection Agency (EPA) and the US Army Corps of Engineers (USACE).
