Turn off Unused HydroStrata Types

Use the HydroStratigraphy Types Table's Edit | Turn Off Unused HydroStratigraphy tool to scan the borehole database and turn off those units not currently referenced in the project database. This can be a handy way to keep unused formation names from being displayed in diagram legends, to reduce the number of formation names linked to the hydrostratigraphy data tables, and to flag those types that can be deleted from the Types Table.

! The unused units will not be removed from the Table, but simply listed without a check-mark in the Show in Legend column.

! You can tell the program to NOT model disabled formations in the HydroStratigraphy modeling settings.


  1. Open your project's HydroStrata Types Table.
  2. Select the Edit | Turn Off Unused HydroStratigraphy option.

    RockWorks will scan the project's HydroStratigraphy data tables to determine which types are referenced there. All un-referenced formations will be shown without checkmarks from the Show in Legend column in the HydroStratigraphy Types Table.

  3. At this point you can close the HydroStratigraphy Types Table (choose File | Exit) and continue your work.
    Or, you can delete any unused formation names by clicking in each row and typing Ctrl+Del (or right-clicking and choosing Rows | Delete).
