Abstract
We had 17 significant rainfalls during 1979-1995 in Ube city. 8 rainfalls of them caused the inundation in the lowland region of city. Tank model is used in this paper to set the criterion water level whether the inundation will occur or will not Try and error analysis presents the parameter set of Tank Model as shown in Fig3. The criterion Tank water level (D line) is obtained D=35mm. If we have the forecast rain curve, we can predict the occurrence of inundation in the city by inputting the rain into the Tank. Several prediction experiments were made by use of the short time point rainforecasting method (PRFM). The results show the present inundation prediction scheme is useful for the urban water disaster prevention action.
