Water Quality Management and Analysis
WQMAP is an integrated modeling system designed to study surface water quality issues. The system allows the engineer or scientist to develop numerical grids, perform hydrodynamic simulations, conduct single constituent pollutant transport and multiple constituent eutrophication studies in a geographic context all from one application.
Applications for WQMAP
- Total Maximum Daily Loads
- Industrial Produced Water Discharges
- Combined Sewer Overflows
- Cooling Water Intakes and Discharges
- Effects of Engineered Structures
Features
- Integrated Geographic Information System
- Grid generation
- Hydrodynamic Model
- Pollutant Transport Model
- Eutrophication Model
- All model use same computational grid
- Applicable within regions such as rivers, lakes, estuaries, bays and coastal seas
