Abstract: 

A numerical simulation model for rainfall-runoff and flood inundation model considering process of individual building inundation was developed. The set-up of this model is based on so-called “urban landscape GIS delineation” that faithfully describes the complicated urban land use features in detail. The flow between single spatial elements is based on established hydraulic and hydrological models with equations that describe all aspects of storm runoff generation in an urban environment. The model was set up and applied for the upper Kanda catchment in Tokyo Metropolis, Japan. The runoff response to a storm event was simulated. It was demonstrated how the model can be used to evaluate the process of building inundation in the urban hydrological system.
