Abstract
Most numerical studies of sediment transport in the swash zone use depth-averaged models. However, such models still have difficulty predicting transport rates and morphodynamics. Depth-resolving models could give detailed insight in swash processes but have mostly been limited to hydrodynamic predictions. We present a depth-resolving numerical model, based on the Reynolds Averaged Navier-Stokes (RANS) equations, capable of modelling sediment transport and morphodynamics in the swash zone.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/PB8Vs0LJq88
Highlights
Most numerical studies of sediment transport in the swash zone use depth-averaged models
MODEL SETUP The model is based on the model by Jacobsen et al, (2014), i.e. based on OpenFOAM to solve the Reynolds Averaged Navier-Stokes (RANS) equations and coupled with a turbulence model
The air-water interface is modelled using a Volume Of Fluid (VOF) scheme
Summary
Most numerical studies of sediment transport in the swash zone use depth-averaged models. MODEL SETUP The model is based on the model by Jacobsen et al, (2014), i.e. based on OpenFOAM to solve the RANS equations and coupled with a turbulence model. We use the stabilized k-ω model by Larsen and Fuhrman (2018).
