The U.S. Geological Survey's Precipitation-Runoff Modeling System (PRMS), an interactive processor for hydrologic modeling and data management called ANNIE, and a modified version of the National Weather Service's Extended Streamflow Prediction (ESP) program have been modified and enhanced for microcomputer application. Watershed-simultion capabilities are provided by PRMS, a modular-design distributed-parameter watershed model. Model input is read from files prepared by ANNIE, and model output can be generated for graphical and statistical analysis by ANNIE. ANNIE helps a user interactively create, check, uptdate, reformat, transform, and statistically and graphically analyze meteorologic and hydrologic data. Forecasting capability is provided by the coupling of PRMS and ESP. ESP prodcuces a probablistic forecast for streamflow variables, such as maximum flow, flow volume, and the date flow decreases below a selected volume.
