摘要： PURPOSE:To forecast the latest amount of rainfall at short intervals of time by calculating the gravity center point of the rainfall amount and rainfall density from a rainfall amount distribution chart obtained by calibrating raindrop data obtained by a radar rain gauge with rainfall amount data obtained by a ground rain gauge. CONSTITUTION:A forecasting device 3 calibrates the raindrop data from the radar rain gauge 1 with rainfall amount data from the ground rain gauge 2 at prescribed intervals of time to generate a rainfall amount distribution chart at prescribed intervals of time, thereby calculating the rainfall amount gravity center and rainfall density. Then the movement track of the rainfall amount gravity center is found from the difference between rainfall amount gravity center points of adjacent times and moved to the gravity center point of a forecasted object area. Further, the transition track of the rainfall density is found from the difference in rainfall density between adjacent times. Further, the future moving speed forecasted value and rainfall density forecasted value are calculated from the moving speed data on the rainfall amount gravity center point and the transition track of the rainfall density. Here, the mean value of the amount of rainfall in an area traced back on the movement track of the estimated object area by a moving speed forecasted value is found and multiplied by a variation coefficient obtained from the rainfall density forecasted value to obtain the rainfall amount forecasted value of the object area to be forecasted.

摘要： PURPOSE:To quickly make an equal-arrival-time curve with reference to various condition changes by installing a means wherein the transfer point of a pipe waterway is computed on the basis of the flow velocity of rainwater flowing inside the pipe waterway. CONSTITUTION:The intensity of a rainfall is received by a radar transmitter- receiver 13 via an antenna 11, and it is transmitted by a data transmission device 14 as precipitation data 15. On the other hand, data from a ground rain gauge 12 is transmitted by a telemeter 16. The data 15 is sent to a precipitation operation device 17, and a precipitation is estimated and sent out to an outflow- analysis operation device 18. The operation device 18 automatically makes an equal-arrival-time curve by using an outflow-analysis support apparatus 20. That is to say, the flow velocity of each pipe waterway is found on the basis of characteristic data on the pipe waterway by a pipe-waterway transfer- point computation means, the transfer time is found on the basis of the flow velocity and the length of the pipe waterway, and a transfer point is computed. After that, a transfer curve is computed on the basis of a prescribed geometrical equation from a most downstream point up to an upstream point, and an equal- arrival-time curve is made on the basis of the transfer curve.

CONSTITUTION: The activated sludge scraped by a sludge scraper 3 in, for example, four sludge accumulating inlets 2 in a settling basin 1 is returned by a return sludge pump 4 into an aeration tank, and the flow rates of the return sludge removed from the inlets 2 are measured with electromagnetic flowmeters 5 for return sludge. The excess sludge is branched from the removal pipings of the respective sludge accumulating inlets and is removed through electrically driven selector valves 6 provided for each of the basins by means of an excess sludge pump 7. The removal flow rate of the excess sludge in this stage is measured with an electromagnetic flowmeter 8 for the excess sludge. When a removal command is emitted to an excess removal command 9 in such constitution, the command is inputted to a calculator 10.
