AbstractA daily disaggregation model developed with summer rainfall data from southeastern Arizona was analyzed for its utility at two midwestern locations, Hastings, Nebraska, and McCredie, Missouri. The model required modification. For example, two distributions required modification and one was replaced. An addition to the model was made to describe the diurnal variation in shower depth for days with one shower. With modifications, the disaggregation model accurately described the daily intermittant rainfall process for the two midwestern locations. Parameter values developed from the Hastings and McCredie's (primary stations) data sets were used to simulate the daily intermittent rainfall at three nearby locations (test stations). Statistical testing indicated that the primary stations' parameter values adaquately simulated the test stations rainfall if the stations were within the same precipitation c1imatologic zone.
