A CUDA Fortran GPU-parallelised hydrodynamic tool for high-resolution and long-term eco-hydraulic modelling

Eco-hydraulic models are wide extended tools to assess physical habitat suitability on aquatic environments. Currently, the application of these is limited short river stretches and steady flow simulations. However, this limitation can be overcome with a high-performance computing technique: graphics processing unit (GPU) computing. R-Iber GPU-based hydrodynamic code parallelised in CUDA Fortran that, integration biological module, performs as an eco-hydraulic numerical tool. was validated applied real cases by using optimised instream incremental methodology long reaches long-term reduces computation time considerably, reaching speed-ups two orders magnitude compared traditional allows for overcoming current limitations simulation high-resolution calculated reasonable timeframe, which provides better representation hydrodynamics habitat.
