Soil erosion and depositional processes result in changes in topographic and soil profile properties over time. In spite of this, few current soil erosion models account for these changes. To begin to address this deficiency, a distributed version of RUSLE2 has been developed and used in combination with the tillage erosion model TELEM (Vieira and Dabney, 2010). These models were applied to a 6.6 ha research watershed near Treynor, IA, where runoff and sediment yield were measured on a daily basis from 1975 through 2002. The watershed contained a grassed waterway and, beginning in 1991, ~1-m wide grass hedges were established with 15.4 m interval between the grass hedges. Beginning in 1996, no-till management replaced conventional tillage management in the watershed.
