Dam break

The video shows the consequence of a breach in a dam of water. The dam breaks in the middle and an outward propagating fast shock wave is formed along with smooth backflow behind the dam. The simulation is performed with an entropy stable Roe type finite volume scheme and shows the water height as it evolves after the breaking of the dam.
