Numerical studies using staggered finite volume for dam break flow with an obstacle through different geometries

Numerical studies using staggered finite volume for dam break flow with an obstacle through different geometries

This paper aims to present a numerical study of dam break flow in the presence of an obstacle. A model based on the modified Non-Linear Shallow Water Equations with cross section and a dispersive treatment was solved numerically using a momentum-conservative finite volume method on a staggered grid....
