General presentation of sediment module SEDI_MARS3DΒΆ

  • Particulate variables are classified into several types
    • gravel : transported bedload
    • sand : transported in suspension
    • mud : transported in suspension
  • Diagram of the main processes related to sediment dynamics :

  • This module adds the settling and flocculation processes to the transport of particulate variables in water column (3D). Deposition on bed sediment and erosion are taking nto account at the water-sediment interface. The sedimentary column is treated 1DV (in each grid cell model), with a variable number of layers whose thickness, porosity and concentration vary with time on demand by sedimentation and resuspension events. The consolidation process may be taken into account, so that the morphodynamic evolution.
