Layer-averaged modeling of turbidity currents with a finite element method

A finite element technique has been applied to the hyperbolic system of partial differential equations for a turbidity current flowing in deep ambient water. Since the standard Galerkin method yields spurious oscillations when applied to convection-dominated flows, the dissipative-Galerkin technique which has a selective damping property, is used. In order to track the moving front numerically, a node-adding method is used for the one-dimensional problem of channelized turbidity currents. For two-dimensional non-channelized turbidity currents, a deforming grid generation technique is employed.
