We developed a GUI system to predict the effect and extent of flood and debris flow. The system has two features. First, the system can extract the target domain using digital elevation model (DEM) data by specifying the LAT/LON of the occurrence site. Second, a raster-based, 2D diffusion wave model was used as a numerical flow model to reduce the computational time. Although this system had difficulty in predicting the impact of micro-topography as a result of the coarse mesh data, overall it satisfactorily represented the scale and potential risk of these disasters. In addition, this system can access DEM data throughout Japan to generate exact target domains. Thus, this system can be used to efficiently predict flood and debris flows at a large number of sites.Keyphrases: dem, diffusion wave model, horizontal 2d simulation In: Goffredo La Loggia, Gabriele Freni, Valeria Puleo and Mauro De Marchis (editors).
