| Abstract | This paper compares a step-wise, multi-scale calibration of a physically-based hydrologic model, DWEPP, to a more traditional calibration performed at a single scale. The Dynamic Water Erosion Prediction Project model (DWEPP; Bulygina et al., 2007) combines the KINematic Runoff and EROSion model (KINEROS2; Semmens et al., 2008), an established physicallybased hydrologic model, and the Water Erosion Prediction Project model (WEPP; Flanagan et al., 2001), a proven process-based soil erosion model. KINEROS2 has been shown to perform well when representing runoff (Miller et al., 2007) but the representation of sediment transport and erosion processes are poor (Canfield and Goodrich, 2006). Using DWEPP, Bulygina (2007) calibrated at plot and hillslope scales and found satisfactory performance of sediment yield dynamics; however, the model was not tested at the small watershed scale and performance across scales, a substantial challenge in both hydrology and erosion models, was not evaluated. The step-wise, multi-scale approach used in this exercise attempts to improve upon traditional calibrations where uncertainty and poor performance are common when moving across spatial scales. |
