A DEM Based Hydrologic and Sediment Transport Modelby Menghua Wang,
Document Type: Proceeding Paper
Part of: North American Water and Environment Congress & Destructive Water
Abstract: A DEM-based, physically-distributed model was developed for simulating event runoff and erosion on an agricultural watershed. Runoff was described using the diffusion equation with flow links determined from the DEM. Interrill soil loss was estimated using rainfall intensity raised to a power and transport by a transport-capacity-deficit relation. The model was applied to Goodwater Creek, a USDA research watershed located in central Missouri. The agreement between the model and the data was good.
