| Outline of Final Research Achievements |
In this study, a numerical simulation model for rainfall-runoff and flood inundation was developed; this model considers the inundation process of individual building. The model was built and evaluated for the upper Kanda catchment, Tokyo Metropolis, Japan. In the model, the parameters for the foundation height and floor height of each building and the opening ratio below and above the 1st floor were set for individual buildings based on their structure and purpose. The model was applied to simulate one major storm event. It could reproduce differences in the inundation depth of individual buildings reflecting the additional input parameters. The use of the model to evaluate the inundate condition for specific properties of the building was also demonstrated.
