Abstract
We present a two-dimensional finite-difference shallow water model for simulating flood and dam-break in an actual terrain environment. This model uses a second-order hybrid type of total variation diminishing (TVD) approximate scheme to solve the shallow water equations. The limiter functions for the TVD scheme, the MUSCL, are used simultaneously in the calculating process. The minimum positive depth scheme (MPDS) was employed to handle the advancement of drying and wetting fronts. Several model problems, including a dam-break flooding over a triangle obstacle, a dam-break in a valley, an estuary with an adverse inconstant slope under a tidal cycle, have been used to verify the model. Finally, we present the physical model with DEM data to simulate dam-break flow in the Hsindian Creek and Pa-Chang Creek in Taiwan. We obtained the realistic and good results. The model also exhibits the potential to provide the basis for computationally efficient flood routing and warning information.
