An Implementation of Adaptive Mesh Refinement for Shallow Water Equations
For researchers using GeoClaw for tsunami or coastal modeling, this reduces computational cost of multilayer simulations, which were previously too expensive for large domains.
This work implements adaptive mesh refinement for multilayer shallow water equations in the GeoClaw framework, enabling efficient simulation on large domains with high resolution in coastal regions.
An implementation of adaptive mesh refinement algorithms is presented for use with multilayer shallow water equations. Currently, adaptive mesh refinement is implemented with a single layer shallow water model in the GeoClaw framework. This implementation, also in the GeoClaw framework, is for multilayer models, which have been implemented in GeoClaw previously. Until now, however, these models were too computationally expensive to run on large domains while resolving detail in coastal regions.
