Abstract
Itis an objective of the study that the author research on a possible methods due to increase for waterpower generation, with reviewing for control manual in the Kusaki dam of multo-porpose . Namely, it is significant that to make decreasing an invalidated outflow discharge at flood outflow , and also to make increasing an effective outflow discharge that change into waterpower generation. As following, we had suggested new system that is said to be beforehand outflow methods in dam control,and simulated base on the hydrological data of Kusaki dam managemwnt during 15 years. Run-off analysis of heavy rain using tank model,a quantitative of an effective outflow discharge and waterpower generation was carried out. Results of this study, it is found that beforehand outflow metod is not only an effective for waterpower generation, but also for flood control.
