Tsunami Inundation Flow Simulation Considering Uncertainties

Abstract

In this research, 2D shallow water equations are expanded by an intrusive polynomial chaos approach for efficient uncertainty quantification in tsunami inundation flows. In this study an uncertain input is given on its bathymetry as well as its initial water height in the Thacker's inundation flow problem. Obtained uncertainty quantification results are compared with (exact) Monte-Carlo simulation results to validate the developed approach.
