Numerical methods for a reliable prediction of long water-wave phenomena : uncertainty quantification for tsunami runup
Résumé
Aim of this study is to present robust numerical methods for shallow water equations permitting to correctly predict long water-wave phenomena. A semi-intrusive and polynomial-chaos based method are coupled with a residual based distribution scheme by considering several sources of uncertainties in the simulation of a long wave runup on a conical island. Stochastic results are assessed by comparing with Monte Carlo results. Numerical solutions are compared with experimental data by displaying a great sensitivity from physical and modelling uncertainties.
