Abstract | In this present work, a meshless procedure named “the finite point method” (FPM) for solving two-dimensional shallow water flow problem is presented. The method is based on the use of a weighted least-square approximation procedure, incorporate with a QR factorization and an iterative adjusts of local approximation parameters. All terms in shallow water equation are discretized via collocation method in a point-wise manner. The stabilization of the convective term in present work is derived from approximate Riemann solver proposed by Roe and the semi-discrete equations are integrated explicitly in time by multi-stage Runge-Kutta scheme. The results obtained from proposed FPM scheme show accuracy comparable with the analytical solutions or other numerical results. Moreover, an adaptive refinement technique is incorporated to carry out a numerical simulation of the 26th December 2004 Indian Ocean tsunami with reliable results, show the good capability of FPM to handle the practical shallow water problems |
