A low-cost system of flood runoff and inundation analyses was developed by combining easily obtainable applications running on a personal computer. The system is composed of three components, that is, the component of the GIS, that for flood runoff analysis and that for flood inundation analysis. Most of topographic data and meteorological data for the GIS component are available in low-cost or charge-free. The developed system was applied to analysis of flooding process in Tsuyama city located in Okayama Prefecture during October 16-18, 1998, which was due to record heavy rainfall caused by Typhoon No.10. The accuracy in the water levels estimated by the developed system was supported by the observed water level data and the information acquired by interviews in field investigations, which shows that the developed system has a great advance in practical use as flood control planning.
