Theses and Dissertations
Soil erosion modeling using terrain analysis holds great potential due to the simplicity of the models, and the ease in running the analysis in a GIS. Terrain analysis of the upper Devils Lake basin was conducted using a 3-meter Light Detection and Ranging-derived digital elevation model. Portions of the Mauvais Coulee and Calio Coulee watersheds in the basin were analyzed to evaluate soil erosion potential and determine if terrain analysis was an accurate tool for modeling erosion in this fairly flat landscape. The analysis used slope, flow accumulation, and stream power index (SPI) within a GIS to identify highly eroded …
