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 include:
- Total Maximum Daily
Loads
- Industrial
Produced Water Discharges
- Combined
Sewer Overflows
- Cooling
Water Intakes and Discharges
- Effects
of Engineered Structures
Features:
