AHGW:Boundary to DIS

Boundary to DIS dialog

The Boundary to DIS tool is accessed by double-clicking on " Boundary to DIS" under the " Features" toolset under the " MODFLOW Analyst" toolset under the " Arc Hydro Groundwater Tools" toolbox.

The following fields are available. Required fields are marked with a icon. Fields marked with a icon may either not be supported or the table doesn't exist.

• Input Boundary Polygon Feature – Click the button to bring up the Input Boundary Polygon Features. dialog in order to specify the name of the boundary polygon features.
• Number of Rows (i) – An integer value specifying the number of rows to be created in the MODFLOW discretization. The rows will be evenly spaced.
• Number of Columns (j) – An integer value specifying the number of columns to be created in the MODFLOW discretization. The rows will be evenly spaced.
• Output DISVars Table – Click the button to bring up the Output DISVars Table dialog in order to specify the DISVars table to be created. This table contains variables associated with the MODFLOW DIS file, such as the number of layers, rows and columns in the grid associated with the MODFLOW model.
• Output DELRC Table – Click the button to bring up the Output DELRC Table dialog in order to specify the DELRC table to be created. The DELRC table is used to store the widths (discretization) of the rows and columns in the MODFLOW model.
• Number of Layers (k) – Optional. An integer value specifying the number of layers to be created in the MODFLOW discretization. By default, one layer will be created.
• ITMUNI (Time Unit) – Optional. The time unit in the MODFLOW discretization. By default, this value is set to undefined. The options include:
  • "0 - undefined"
  • "1 - seconds"
  • "2 - minutes"
  • "3 - hours"
  • "4 - days"
  • "5 - years"
• LENUNI (Length Unit) – Optional. The length unit in the MODFLOW discretization. By default, this value is set to undefined. The options include:
  • "0 - undefined"
  • "1 - feet"
  • "2 - meters"
  • "3 - centimeters"
