Abstract: Iber is a two-dimensional hydraulic model for the simulation of free-surface flow in rivers and estuaries and solves hydrodynamics, turbulence, sediment transport, water quality processes, and habitat. Although Iber profits from some kind of OpenMP parallelization, in cases with a large number of computational elements, Iber will need days for completing the calculations which will make Iber almost unusable in applications where a short computational time is needed like flood warning systems. RIBER is a software that was implemented based on the Iber code such that no substantial modifications were made to the original algorithms. With the help of GPU computing using CUDA, it profits speedups up to almost 15 times faster than Iber. This speed up not only will make RIBER more affordable for flood early warning systems but also doing calibration for different cases using stochastic models is more applicable to it.
