Abstract: The mathematical model for simulating suspended sediment transport under equilibrium and non-equilibrium situations is described. Using the hydrodynamic variable field obtained from a refined turbulent free surface flow model, the suspension transport model involves bed boundary conditions for either the sediment flux to or from the bed, or an estimated concentration level, which are tested. The Schmidt number variability is also studied for several particle types. Some 2D vertical test cases for equilibrium situations or non-equilibrium situations with net erosion or net deposition flux to the bed are presented, and the predicted development of the concentration profiles is compared with measurements.
