dc.description.abstract
Two-dimensional shallow-water schemes on Cartesian grids are amendable for graphics processing units and thus a convenientchoice for fast flood simulations. A comparison of recent schemes and validation of important use cases is essential for developersand practitioners working with flood simulation tools. In this paper, we discuss three state-of-the-art shallow-water schemes: a first-orderupwind scheme, a second-order upwind scheme, and a second-order central-upwind scheme. We analyze the advantages and disadvantagesof each scheme on historical Danube river floods at three regions in Austria. We study the Lobau region as a floodplain with severalsmall channels, the Wachau region with the meandering Danube in a steep valley, and the Marchfeld region located at the river confluenceof March and Danube. The validation case studies show that the second-order schemes provide better estimates of the water levels thanthe first-order scheme. Still, the first order scheme is useful because it offers fast simulations and reasonable results at higher resolutions.The best trade-off between accuracy and computational effort for simulating river floods is provided by the second-order upwind scheme.
