In this study, a soil erosion model to identify transitional overland flow regions was developed using the kinematic wave overland flow theory. Spatial data, including digital elevation models (DEMs), soil, and landcover, were used in the GIS-based model algorithm. The model was calibrated and validated using gully head locations in a large agricultural watershed, which were identified using 1-m aerial photography.Steel nails fixed on the center of wood stakes surrounding the edge of the plots defined surveying points. A survey-grade total station (Nikon model) was used for generating elevation data. One location at each site was set as a benchmark and anbsp;...
