ABSTRACT:
Storm water pumps drain storm water in a pump well. In order to control the storm water pumps, a radar rain gage and ground raingages are set. Measurement data from the radar rain gage and the ground rain gages are supplied to a data processing unit. The data processing unit calibrates rainfall distribution data representing a two-dimensional rainfall distribtuion state obtained by the radar rain gate by the measurement data from the ground rain gages, and forecasts a rainfall in a predetermined time from the present from several sets of the calibrated rainfall distribution data. The data processing unit performs runoff analysis corresponding to characteristics of a drainage basin on the basis of the forecast rainfall to calculate a rainfall flow, thereby forecasting a flow of storm water flowing in the pump well. The data prcessing unit determines the number of pumps to be operated in consideration of the flow of storm water flowing in the pump well, a water level of a water level gauge, and the number of currently operating pumps, thereby controlling an operation of the storm water pumps.
