Fully well-balanced entropy stable Godunov numerical schemes for the Shallow Water equations with the topography source term
Résumé
This work concerns the design of well-balanced entropy stable numerical schemes for the Shallow Water equations. The fully discrete entropy inequality is reached with a local condition incorporated in the scheme design. The source term is discretized to preserve the steady states and the entropy stability. The method yields explicit schemes. We illustrate the schemes relevancy with several tests cases in the wet and dry areas.
