A coupled hydrodynamic (HEC‐RAS 2D) and water quality model (WASP) for simulating flood‐induced soil, sediment, and contaminant transport

Abstract Increased intensity and frequency of floods raise concerns about the release and transport of contaminated soil and sediment to and from rivers and streams. To model these processes during flooding events, we developed an External Coupler in Python to link the Hydrologic Engineering Center‐...
