Konstantina Tsiamoura: Uncertainty Quantification in Tsunami Simulations

A Monte Carlo method is used for approximating shallow water equations with random bathymetry inputs. More specifically, the approach described in “Mishra et al. (2010) Multilevel Monte Carlo Finite Volume Methods For Shallow Water Equations With Uncertain Topography In Multi-Dimensions” is used for quantifying the uncertainty of tsunami simulation performed by the SWE code. Because of the slow convergence of Monte Carlo, a Multi-Level Monte Carlo algorihtm is also used, where samples are drawn simultaneously from a hierarchy of grid levels.
