Nicolai Schaffroth: Simulation of rain-induced floods on high performance computers

To allow the simulation of rain-induced floods based on the shallow water equations, several additions and modifications were made to the SWE code base and the HLLE solver. The code, which was originally designed for tsunami modeling, was adapted for better precision at wet-dry interfaces and low water heights. The algorithms and data structures were updated to account for new parameters in the scenarios, including rainfall and friction. Several test scenarios and comparisons with benchmark solutions demonstrate the capabilities and limitations of the HLLE solver implementation.
