Abstract: Sediment solvers using an Eulerian approach have been made in the OpenFOAM CFD library. The latest developments include algorithms computing bed elevation changes based on an adaptive grid for the bed and the free water surface. The vertical movement of the bed is based on the pick-up rate of the particles given by a sediment transport formula. The free surface movement is based on the computed pressure field. The model has been tested for local scour around a vertical circular cylinder and the results compared with an empirical formula. The results are presented together with the free surface algorithms showing the water elevation around the cylinder.
