GWT-IC

Structure of Blocks

FOR EACH SIMULATION

    BEGIN OPTIONS
      [EXPORT_ARRAY_ASCII]
    END OPTIONS

    BEGIN GRIDDATA
      STRT [LAYERED]
            <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.

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