Abstract

An advanced inundation flow model based on the unstructured meshes is newly developed, which can treat suitably the shapes of linear structures such as small rivers and continuous banking. In this model, small rivers can be treated as rectangular channels which comprise a series of meshes with lower elevation and continuous banking can be treated as linear boundary walls. From the obtained results it can be concluded that this model can evaluate the influence of small rivers and continuous banking successfully and can be applicable for inundation flow prediction in urban area. 1 Introduction In most of the existing inundation flow models, the Cartesian coordinate system has been adopted because of its easiness of mesh generation [1]. This coordinate sy
