A Rainfall Runoff Forecasting System (RRFS) is developed as a toolkit for quantitativeand qualitative analysis of basinwide rainfall-runoff relationship. The RRFS consists of four different modules: 1) a real-time hydrologic input data preparation module, 2) a runoffsimulation and forecasting module for providing short-term water demand and supply over 10days based on predicted meteorological data, 3) a runoff prediction module for establishinglong-term water supply plan in reservoir operation, and 4) a graphic visualization module for output display from the simulation and prediction results.Calibration and verification were made by applying the system to the Geum river basinwhich is the third largest river basin in Korea. Since the results of applying the systemshowed fairly satisfactory performance in identifying the status of water resources in the basin and establishing the outlook of water supply, it is expected that the RRFS will serve as an efficient toolkit to provide the spatial and temporal runoff forecasting with water information in the Geum basin. |
