| Research Abstract |
The Tokyo Storm Runoff model is developed and tested. The set-up of this urban catchment-based 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 thus simulates both the conceptually different flooding processes related to overflow from a river and surcharge from a sewer system, respectively. The model was set up and evaluated for the lower Ekota catchment and the upper Kanda catchment in Tokyo Metropolis, Japan. the results show that the suggested approach, based on a detailed reproduction of all relevant elements in an urban catchment, is able to simulate all aspects of urban flooding with high accuracy.
