This paper presents a method to form short cyclic design hyetograph by using data of a Radar raingauge for the simulation program we have developed. The program named stormwater pump operator supporting (SPOS) system has been so far designated to calculate in online operations. This time, we add an offline mode of the program for pump operators' training. Stormwater pumps are, if necessary, turned on or off by every calculation interval of some minutes, so design hyetograph as an input of the SPOS system has, instead of hourly cycle of observation, the same short cycle of the pump. For this purpose, data of Radar raingauge are suitably employed. We regard rainfalls as a Markovian process and make an algorithm in a frame of the dynamic programming by R. Bellman. Calculation results are shown.
