Use of rainfall-simulator data in precipitation-runoff modeling studies

Purpose and scope: The primary purpose of the study is to determine if data on infiltration and runoff obtained from the U.S. Geological Survey rainfall simulator, are useful in defining parameters used in the PRMS, which is used to predict runoff from larger watersheds. Incidental to this purpose are determination of the spatial variability of the parameters measured over the simulation plots and over the watershed, and sensitivity of these parameters in predicting runoff.
