Abstract

To develop a sediment budget for the Le Sueur River, this study implemented a process-based watershed hydrology and upland erosion model, Water Erosion Prediction Project (WEPP), to simulate hydrology and sediment dynamics in several land-use/land-cover scenarios. The Geo-spatial interface for WEPP (GeoWEPP) was used to characterize upland overland flow elements based on their land use/land cover, soil, and slope profiles. These characteristics were used as inputs for the WEPP model to estimate runoff fluxes, soil loss rates, and sediment delivery ratio (SDR) for 3 environmental scenarios : 1) current land-use/land-cover with agricultural lands under fall mulch till management; 2) current land-use/land-cover with agricultural lands under no till management; 3) pre-settlement land-use/land-cover. Over a simulated 30-year period (1979–2008), the runoff depth, soil loss rate and SDR were estimated for each scenario and discussed
