Abstract
A rotating boom rainfall simulator was used on 3 x 10.7 m plots to determine Universal Soil Loss Equation (USLE) parameter values. Simulator runs were made in the spring and fall of 1981 on two replications of four treatments on three soil types in southeastern Arizona. The treatments were: natural, vegetation removed, erosion pavement and vegetation removed, and tilled (moldboard plowed and disked). Runoff, infiltration, and soil loss varied significantly between treatments and, most interestingly, between the spring and fall runs. Plot surface characteristics of rock, gravel, soil, litter, and vegetation cover could not explain this seasonal variation in hydrologic response.
