Initialization of sediment

• The sediment is defined initially by :

  • either with an uniform bottom sediment (if l_unised = .TRUE.), set in paraMUSTANG.txt (namelists for sediment - module MUSTANG)

    • 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

    • l_repsed must set to .TRUE. in paraMUSTANG.txt (namelists for sediment - module MUSTANG)
    • and the name of the file to be read (file_repsed)

  • 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, or build a Netcdf file to read as a save file (see previously file_repsed)
