文摘

Shallow Water Equations parallel numerical scheme suitable for GPU. Novel Block-Uniform Quadtree (BUQ) grid-type, exploiting the computational capability of GPUs with non-uniform resolution. Very large domain can be simulated (38 km river reach) with high resolution (2 m). Speed-up of one order of magnitude is achieved, in comparison with Uniform resolution Cartesian Grids. High ratio between physical and computational time which enables real-time simulations.
