| 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 |
