  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.
