A methodology is developed for the generation of intermittent small-time-interval (15-min.) precipitation. This methodology consists of three components: a probabilistic wet-and-dry sequence component; a Markovian precipitation distribution component; and a regressive spatial-distribution component. The theory of stochastic hydrologic modeling is described and procedures by which this theory can be applied to a hydrologic time series are presented. In particular, the application of the procedures to small-time-interval-intermittent hydrologic processes is given. The methodology is demonstrated by application to an actual precipitation network, the Boneyard Creek raingage network in Champaign-Urbana, Illinois, U.S.A. The trend in frequency of precipitation amounts from the 89-yr. Morrow plots data are produced by the model using 13-yr. of historical data. © 1984.
