PDFAbstract: In this paper a dam-break flood model based on a contravariant integral form of the shallow water equations is presented. The equations of motion are numerically solved by means of a finite volume-finite difference numerical scheme that involves an exact Riemann solver and is based on a WENO reconstruction procedure. An original scheme for the simulation of the wet front progress on the dry bed is adopted. The proposed model is used to simulate the Rio Fucino dam-break and subsequent flood wave propagation, downstream of the Campotosto reservoir (Italy).
