Check it Out! EPA Modeling Tools for TMDLs

The U.S. Environmental Protection Agency (EPA) Hydrological Simulation Program-Fortran (HSPF) model simulates watershed hydrology and the movement of pollutants over pervious and impervious land, as well as instream channels. The accuracy of modeling channel hydraulics is important for proper total maximum daily load estimation. Therefore, EPA created best management practice tools for the model, which […]
