Summary

We present numerical comparisons for the simulation of unsteady 2D shallowwater flows over topography with wet/dry fronts, between well-balanced cell-centered andnode-centered formulations of a finite volume high-resolution algorithm. In both formulationswe utilize Roe’s Riemann solver, while second-order spatial accuracy is achieved withMUSCL-type reconstruction techniques. Grid refinement studies are emphasized
