Numerical modelling of shallow water flow in two dimensions is presented in this work with the results obtained in dam break tests. Free surface flow in channels can be described mathematically by the shallow-water system of equations. These equations have been discretized using an approach based on

In this paper, the subcritical compressible small disturbance equation is employed to simulate the nonlifting flow over a 6% thick circular arc. The governing nonlinear elliptic boundary value problem is solved numerically with the collocation finite element technique using the Hermite bicubic shape
The unsteady free surface flow caused by sudden collapse of a dam produces discontinuities in the flow variables. As the flow surges downstream, it forms a moving bore front with steep gradients of water height and velocity. In the numerical simulation of this flow, proper grid distribution can play
