ENHANCING THE SEDIMENT TRANSPORT MODELING CAPABILITY OF A WATERSHED MODELING FRAMEWORK

The Strategic Environmental Research and Development Program (SERDP) identified the need to provide Fort Benning, Georgia (and eventually other military installations) with models that can be implemented for long-term watershed planning and management. This paper discusses one of the objectives of this SERDP-funded project that focuses on the development of a watershed modeling system for Fort Benning, GA using the U.S. EPA BASINS (BASINS) modeling framework. The project objective described in this paper is the enhancement of BASINS through the integration of more robust models for channel flow (EFDC) and channel sediment transport (SEDZLJ) into BASINS, as well as the capability to represent channel bank erosion using an empirical bank erosion algorithm. This paper reports the project's approach for accomplishing the stated objective.
