Abstract: The potential of water disaster in urban area increases by urban development and frequency of heavy rain. Despite of increasing demand for establishment and examination of measures on water disaster, development of numerical simulation model dealing with complex urban water behavior is not sufficient. Moreover, a lot of input data is required prior to simulation. The input data preparation system must be firstly developed for numerical analysis of inundation water behavior in urban area. The analysis system with three subsystems, the data preparation subsystem, the inundation analysis subsystem in urban area and the demonstration subsystem of analysis results is developed in this study. In this system, the inundation analysis subsystem can simulate the complex behaviors of water flow in river, channel, sewer system and urban area and their interactions. This system also comprises the demonstration subsystem. This inundation analysis system is very useful for evaluation and establishment of measures on water disaster in urban area.
