Initialization of sedimentΒΆ

  • The sediment is defined initially by :

    • either with an uniform bottom sediment (if l_unised = .TRUE.), set in parasedim.txt (namelist for sediment : parasedim.txt)

      • hseduni : initial uniform sediment thickness(m)
      • cseduni : total initial sediment concentration
      • ksmiuni : lower grid cell indices in the sediment
      • ksmauni : upper grid cell indices in the sediment
      • sini_sed : initial interstitial water uniform salinity
      • tini_sed : initial interstitial water uniform temperature
      • csed_mud_ini : mud concentration into initial sediment (if =0. ==> csed_mud_ini=cfreshmud)
      • concentrations of each particulae variable will be give in variable.dat (Definition of parameters for particulate-sediment substances in variable.dat)
      • If there is a mixing of sand and mud, the initial total sediment thickness is automatically adjusted according to selected parameters and initial concentrations chosen for each type of sediment.
    • either reading a saved file, issued from a previous run

    • either defined by the user from knowledges of facies or mud fraction ....
      • In this case, user must write the program, dependent on his configuration and data.
