Technical Abstract: Quantifying changes in potential soil erosion under projections of changing climate is important for the sustainable management of land resources, especially for regions dominated by agricultural land use. One of the expected changes to climate in the future is an increase in the frequency and intensity of rain events. The recently developed VIC-WEPP (Variable Infiltration Capacity - Water Erosion Prediction Project) coupled model was utilized to quantify changes in potential soil erosion by water under three climate change scenarios (a1b, a2b, b1) using projections from three global climate models (GFDL, PCM, HadCM3) for the Great Lakes region. Soil loss estimates were developed for thirty year periods for the current century, and compared to estimates for a thirty year historical period. Relative changes in precipitation, freeze-thaw state of the soil, snow cover and other hydrologic metrics were used to explain changes in erosion potential, and regions with large projected changes in erosion risk were identified. The results may be useful for targeting future erosion control efforts and/or conservation funding.
