Abstract
Unstructured meshes are becoming more and more popular in geophysical flow models. We present a two-dimensional model solving the shallow water equations on unstructured meshes. The latter is dynamically adapted using the AMR technique to minimize the discretization error. The interpolation order is also adapted during the solution process. Classical test cases on the sphere are used to validate the model, as well as the global simulation of the 2010 tsunami in Chile.
