Abstract: A depth-averaged two-dimensional (2D) numerical model for unsteady flow and nonuniform sediment transport in open channels is established using the finite volume method on a nonstaggered, curvilinear grid. The 2D shallow ...

Abstract: A simplified physically based model has been developed to simulate the breaching processes of homogenous and composite earthen embankments owing to overtopping and piping. The breach caused by overtopping flow is approximated ...

Abstract: A three-dimensional (3D) numerical model has been developed to simulate dam-break flows with sediment transport over movable beds. The hydrodynamic model solves the 3D Reynolds-averaged Navier-Stokes equations using a ...

Abstract: A one-dimensional model has been established to simulate the fluvial processes under dam-break flow over movable beds. The hydrodynamic model adopts the generalized shallow water equations, which consider the effects of ...

Abstract: Several existing formulas for the initial porosity and settling velocity of sediment have been tested by using extensive data collected from different countries and regions, and modified to achieve better reliability or ...
