Abstract

A two-dimensional (2D) finite volume model that uses a first order upwinding scheme to simulate dam break floods over a complex topography, represented by a digital elevation model (DEM), was enhanced by implementing a two-sided cut-cell boundary method to represent linear terrain features, such as road and railroad embankments, which may significantly influence flood propagation and delineation. A special version of the cut-cell boundary is implemented to provide coupled 1D-2D simulation capability.
