Description

In analysis of two-dimensional overland flood flow, Cartesian coordinate has been used most popularly. However, in application of the coordinate to urban area, some difficulties arise for treating urban geographical factors - streets, buildings, small rivers or continuous dike -, which have large influence on inundation flow. Then in this paper, an inundation flow model using unstructured meshes which can divide the computational region into arbitrary shapes of meshes is developed, and applied to urban area.Consequently, it is found that this model can take small rivers and continuous dike into account and can be applicable for predicting an inundation flood hazard in urban area.
