Abstract

Serial estuarine hydrodynamic and sediment transport model is parallelized by MPI method based on domain decomposition techniques, the parallel model is applied to a hydrodynamic example of tidal current and sediment transport in the estuary and offshore area of Zhejiang in China. The benchmark result shows that MPI method has good parallel effect, whose speedup is accessible to 41 by 80 processors. Simulations of the annual sediment transport by tidal currents in local region have been reduced to less than one day of compute time.
