+abstract = {A GPU-parallel numerical model for the solution of the 2D Shallow Water Equations, based on a novel type of grid called Block-Uniform Quadtree (BUQ), is presented. BUQ grids are based on a data structure which allows to exploit the computational capability of GPUs with minimum overheads, while discretizing the domain with non-uniform resolution. Different cases have been simulated in order to assess the efficiency of the BUQ grids. Theoretical and laboratory tests demonstrate that speed-ups of up to one order of magnitude can be achieved in comparison with uniform Cartesian grids. In the simulation of a hypothetical flood event induced by a levee breach in a real 83\'{z}km long river reach, with maximum resolution of 5\'{z}m, a ratio of physical to computational time of about 12 was obtained, opening scenarios of quasi real-time 2D simulations in large domains, still retaining a high resolution where necessary. 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\'{z}km river reach) with high resolution (2\'{z}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.},
