Computation of non-cohesive sediment transport in estuaries by a fluid-particle, two-dimensional model

摘要

This paper presents a 2-D fluid-particles model for computing seidment transport in estuarine zones. This model is based on resolving the mass, momentum and constitutive equations for free-surface and multi-phase flows. The fluid-particles and particle-particle interactions are taken into account in the model. Chorin's method combined with a finite differences technique is use.d Benchmark tests, which describe the suspended-sediment transport, and the flow engendered by solid-particles settling in a reservoir, have been realised to validate the present model.
