AbstractIn this study, model parameters were estimated using five different watershed configurations for the SWRRB (A Basin Scale Simulation model for Soil and Water Resources Management) model, based on soil types and vegetation characteristics for watershed 11 in the Walnut Gulch Experimental Watershed in Tombstone, Arizona. Different watershed configurations were used, starting with one subbasin, up to a maximum of five subbasins. GIS was used to delineate the subbasins and to calculate some of the input parameters. Surface runoff was simulated for a period of six years (1982-1987). The simulated runoff values were compared with observed values. In addition, this study evaluated the effects of watershed configuration on runoff prediction by the SWRRB model.
