1D modelling of dam-break surges with floating debris

To predict flood and debris flow dynamics a numerical model ,based on 1D De Saint Venant (SV) equations, was developed.The McCormack-Jameson shock-capturing scheme was employed for the solution of the equations ,written in a conservatine-law form.The model proposed can easily be extended to channels with arbitrary cross sections for debris flow routing,as well as for solving different problems of unsteady flow in open channels by incorporating the appropriate initial and boundary conditions.
