Abstract: A two-dimensional numerical model for local scour under a submarine pipeline is established. By using finite volume method with SIMPLEC algorithm, the unsteady Navier-Stokes equations combined with k- turbulence model are solved. A cut cell approach enables the model to simulate the scour process from sitting-on-bed-pipeline status to suspended-pipeline status without re-generating the mesh in conventional sense. The transports of bed load and suspended load of uniformly noncohesive sediment are modeled to simulate the local scour process.
