Abstract

A finite element numerical model is proposed for the simulation of 2-dimensional turbidity currents. Time-dependent, layer-averaged governing equations, a hyperbolic system of partial differential equations, are employed. The Petrov-Galerkin formulation is used for the spatial discretization and a second-order finite difference scheme is used for the time integration. A deforming grid technique based on the Arbitrary Lagrangian-Eulerian description is employed to cope with the moving boundary of a propagating front. The developed numerical algorithm is applied to the simulation of laboratory observations.
