PURPOSE:To invariably perform proper operation control by predicting the rainfall based on the data of a radar ombrometer and ground ombrometers and determining the number of rain pumps to be operated based on the inflow quantity to a pump well and the water level in response to the predicted rainfall. CONSTITUTION:Two-dimensional rainfall distribution is measured by a radar ombrometer constituted of a radar antenna 1 and a radar transmitter/receiver 2 or the like. The ground rainfall is measured by ground ombrometers 5 installed at multiple places. The data of the ombrometers are fed to data transmission devices 4a and 4b and telemeter devices 6a and 6b then corrected by a means 7, the rainfall is predicted by a means 9. The outflow analysis is performed by a means 10 based on the predicted rainfall, the inflow quantity to a pump well 21 is calculated. The number of pumps to be operated is determined by a means 11 based on the inflow quantity to the pump well 21 and the water level of a water level gauge 22, rain pumps 24 are operated by a control means 23 via a driving means 25. |
