Description
Most models are unable to capture scour onset of a slightly buried pipeline due to the unresolved seepage process. This study used a two-phase model, SedFoam, to simulate scour onset process under different forcing conditions, such as current and waves. The model was further applied to the backfill process. Simulations showed good agreements with experiments and demonstrated the capability of SedFoam.
