MORPHOLOGICAL CHANGE SIMULATION USING A GPU-BASED PLATFORM

With the advancement of parallel computing in hydrodynamic models, computational burdens have significantly decreased compared to the past. Modelling based on Graphics Processing Unit (GPU) is one noteworthy method in achieving this improvement. Moreover, GPU computing can be an attractive tool not only for hydrodynamic models but also for morphological simulations. Several trials of sediment transport model using GPU shows advanced performance in terms of computational efficiency. In this study, we developed the sediment transport model to simulate the movement of sediment and morphological changes based on the GPU based platform Celeris Advent (Tavakkol and Lynett, 2017). Celeris Advent is a coastal wave solver capable of real-time numerical simulation and visualization using GPU acceleration.
