Abstract
In this paper, possibility of dam control system applied to both neural networks and fuzzy set theory for supporting reservoir operation is investigated. The authors put the hydrological information of precipitation and predicted inflow discharge etc., and also the information of the past operated by actual operator, into the dam supporting system. In this system, neural networks are applied to the decision of the operational line of reservoir operation for release discharge from reservoir, constant water level and the storage volume and fuzzy set theory is applied to the decision of the operational volume of reservoir operation for the release discharge from dam reservoir. As the result compared with actual operator's operation, it is indicated that dam supporting system using both neural network and fuzzy system is able to apply to the operation for flood control
