The quality of the results of computer modeling relate to the quality of input data. For this thesis the impact of two digital elevation model resolutions on a best management practices analysis method utilizing the Soil and Water Assessment Tool (SWAT) was analyzed. The tool model outputs targeted were stream flow and sediment yield. The study area was Burnt Creek. Burnt Creek is a small ungauged watershed in the Bad River in western South Dakota. Different BMPs were simulated by varying upland and channel conditions. Results of the analysis showed a less than one percent difference in flow reduction between the two models and a less than three percent difference reduction in sediment yield between the models.
