Abstract: A joint international collaboration between the Korea Water Resources Corporation (KOWACO) and Colorado State University (CSU) has resulted in development of a decision support system (DSS) for daily operations in the Geum River Basin, Korea. The DSS is a customized version of the MODSIM Generalized River Basin Network Flow Model, which has been calibrated for the Geum River Basin in particular and Korean conditions in general. It is shown that customization of MODSIM is accomplished without the need for any recoding of the model, but rather through use of embedded PERL script. The graphical user interface is translated into the Korean language for ease of use by KOWACO engineers and system operators. The model is not only calibrated to physical and hydrologic characteristics of the basin, but also to normal and emergency operating rules utilized by the water managers and engineers. The DSS provides daily operational guidance for multipurpose operation of system reservoirs to meet municipal and industrial water requirements, irrigation water supply, instream flow conditions for water quality management, and hydropower generation. Flood control purposes are indirectly considered through management of seasonal flood control space in the reservoirs. Experience with actual implementation of the DSS for daily real-time operation is reported.
