摘要：

This paper presents a recently developed flood propagation model. In order to use graphics processing unit (GPU) acceleration, (i) the domain shallow water equations are simplified by linearizing bottom friction and neglecting advection, and (ii) an appropriate vectorization method is implemented. The model solves the finite difference scheme for each pixel of large-scale raster maps (i.e., regional or national ones). It was initially tested against a well-known benchmark and was then applied to a coastal flooding event in the Caorle area, Venice, Italy, which occurred in December 2008.
