Abstract
In considering a countermeasure against urban flooding, it is necessary to predict inundation flooding exactly. In this study, it is aimed to develop inundation flow models which can take account of streets and buildings in urban area. Cartesian coordinate, Generalized curvilinear coordinate, Unstructured meshes are applied to inundation flow analysis, and Street network model is also developed. Their results are compared with one another. These models have their own characteristics, therefore, in accordance with characteristics of the computational area or required accuracy of the results, the proper choice of these models will lead to advanced inundation analysis in urban area.
