Discontinuous Galerkin method for coupling hydrostatic free surface flows to saturated subsurface systems
arXiv:1806.03909
Abstract
We formulate a coupled surface/subsurface flow model that relies on hydrostatic equations with free surface in the free flow domain and on the Darcy model in the subsurface part. The model is discretized using the local discontinuous Galerkin method, and a statement of discrete energy stability is proved for the fully non-linear coupled system.
