Numerical modelling of flood problems has become more and more complex. Consequently, the computational requirements, particularly for computing very large domains, have been increasing rapidly. To deal with these problems, parallel computing can be a choice. The topic of this research is “High Performance Computing of Coupling 2D and 3D Numerical Modelling of Flood Propagation and its High Performance Interface and Visualisation”. In this research, the 2D (non)-hydrostatic model will be coupled with the 3D non-hydrostatic model to simulate flood propagation problems within a framework of hybrid programming which combines the OpenMP and MPI parallelisation technique. For areas where wet-dry interfaces are dominant or vertical profiles are not of main interest, the 2D model is employed, whereas the 3D model is applied for areas where non-hydrostatic pressure condition applies, e.g. vertically circulating flows. Our code will be performed using the OpenMP for shared memory parallelisation inside of each node and communicated with other nodes using the MPI which is developed for distributed memory parallelisation. Using this hybrid model, some advantages, such as eliminating domain decomposition at node and lower memory latency and data movement within node, can be achieved.
