GWT-IC

Structure of Blocks

FOR EACH SIMULATION

    BEGIN OPTIONS
      [EXPORT_ARRAY_ASCII]
      [EXPORT_ARRAY_NETCDF]
    END OPTIONS

    BEGIN GRIDDATA
      STRT [LAYERED] [NETCDF]
            <strt(nodes)> -- READARRAY
    END GRIDDATA

Explanation of Variables

Block: OPTIONS

EXPORT_ARRAY_ASCII keyword that specifies input griddata arrays should be written to layered ascii output files.
EXPORT_ARRAY_NETCDF keyword that specifies input griddata arrays should be written to the model output netcdf file.

Block: GRIDDATA

strt is the initial (starting) concentration—that is, concentration at the beginning of the GWT Model simulation. STRT must be specified for all GWT Model simulations. One value is read for every model cell.

Example Input File

    #The OPTIONS block is optional

    #The GRIDDATA block is required
    BEGIN GRIDDATA
      STRT LAYERED
        CONSTANT   0.0  Initial Concentration layer   1
        CONSTANT   0.0  Initial Concentration layer   2
