GMS:Managing Transient Data Workflow

Transient data in an existing MODFLOW project can be managed with the following steps:

1. Enter transient data into the Map module.

1. Manually enter transient data. Using the Select Arc , Select Points/Nodes , or Select Polygon tool, double-click on a feature object to receive the transient data. In the Attribute Table dialog, change a rate field to "<transient>" and select the button. Enter transient data in the XY Series Editor dialog. 2. Import transient data. Select the Map module coverage that will receive the transient data. Use File | Open... to open files with transient data. Use the Text Import Wizard to specify how to import the data. In step 2, select a transient GMS data type.

2. Initialize MODFLOW stress periods.
1. Change MODFLOW simulation to transient. Select the MODFLOW | Global Options menu command. Select Transient in the MODFLOW Global/Basic Package dialog. 2. Set up stress periods. Select the MODFLOW | Global Options menu command. Select the Stress Period button in the MODFLOW Global/Basic Package dialog. Enter stress period parameters in the Stress Periods dialog.

3. Map to MODFLOW.
Select the conceptual model . Select Feature Objects | Map → MODFLOW . Select the appropriate options in the Map → Model dialog.
