Abstract

PURPOSE:To always minimize errors of assumed inflow of rainfall with respect to the true inflow without impairing hourly followup, by averaging certain times of assumed inflow of rainfall to determine the average assumed inflow. CONSTITUTION:Rainfalls from a plurality of rain gauges 121-12n provided on the upper valley of a dam are inputted into a dam valley average rainfall calculating circuit 13 to calculate the average rainfall RS, which then, is inputted into a continuous rainfall judging circuit 14 to judge the continuous rainfall while the integrated value Rot of the continuous rainfall is calculated. Subsequently, an inflow calculation interval detecting circuit 15 determines the inflow calculation interval N based on the integrated value Rot of the continuous rainfall and outputs the interval N to an inflow calculating circuit 16. Based on the interval N, the inflow calculating circuit 16 averages the assumed inflow Qi given from an assumed inflow calculating circuit 9 only by N times and outputs the resulting average assumed inflow Qio. This can minimize errors of assumed inflow due to disturbance of the water level of the dam or the like without impairing the timewise followup.
