项目摘要

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.

东京风暴径流模型的开发和测试。该模型的建立是基于城市景观地理信息系统（GIS），它忠实地描述了复杂的城市土地利用特征。单个空间要素之间的流量是基于已建立的水力和水文模型，其中的方程描述了城市环境中暴雨径流产生的各个方面。因此，该模型分别模拟了与河流溢流和下水道系统超载有关的概念不同的洪水过程。该模型的建立和评价，在东京大都会，日本的下Ekota流域和上神田流域。结果表明，所建议的方法，基于详细再现的所有相关要素在一个城市集水区，是能够模拟城市洪水的各个方面，具有较高的精度。
