Implementation of sediment module SEDI_MARS3D
---------------------------------------------

* The implementation of this module requires to use the module substance (:ref:`implementation_substance`) and complete :

   * a **new namelist file** (:ref:`doc_parasedim`), 
   * the **data file** (:ref:`doc_variabledat`), with sedimentlogic parameters for each particulate substance  (:ref:`definition_parasubstancesed`)
   * and if necessary files defining the (:ref:`boundaries_substance`) ; (:ref:`initial_substance`) and (:ref:`doc.sedim.initial`) 
   * and if necessary concentrations in inputs 
       * :ref:`river_substance` 
       * and :ref:`atmospheric_substance`

* This module creates **output files** for saving results in sediment. These file's names are the same as those for results in water column, with the additional word "_sed_". There are differant ways to save variables in sediment (:ref:`sedim_output`).

* This module creates a **restart file** also "*save_sedim.nc*" (if *l_saverestart_1file=.true.*) or several  restart file if *l_saverestart_bydate=.true.*.
 
* User can choose to use sediment with **consolidation** or not (:ref:`doc_consolidation`) (l_consolid =.TRUE. in parasedim.txt)

* Dissolved variables are included in the sediment layer and can diffuse threw sediment-water interface if l_diffused=.true. in parasedim.txt (:ref:`doc_diffused`)
* User can choose to couple **morphodynamic** (:ref:`doc_morphocoupl`) (l_morphocoupl =.TRUE. in parasedim.txt)
* The coupling between the module SEDI-MARS and the module ECO-MARS is now possible in order to compute suspended matter in the water column taking account erosion and deposit processes, and also to follow biogeochemistry into the sediment with fluxes at interface water/sediment (:ref:`coupl_biolo_sedim`)
