摘要
We consider the non-hydrostatic system derived by Yamazaki et al. for shallow flows. This model consists in the well known shallow water model which is coupled with two additional equations corresponding to non-hydrostatic terms. We develop a second-order well-balanced numerical method which combines finite-volume and finite-difference schemes. The numerical scheme has been implemented in GPUs and has been applied to idealized and challenging experimental test cases. The test cases show the accuracy and efficiency of the scheme.
