SEEP2D Project Workflow

This is a top level workflow. This workflow includes all of the specific workflows needed in creating a general SEEP2D model project using the conceptual model approach. Newer and infrequent GMS users should start here.

To build a SEEP2D model in GMS, use the following steps:

1. Change the GMS program mode.
Launch GMS. Select the Edit | Preferences menu command. In the Program Mode section of the Preferences dialog, select the "GMS 2D" option.

2. Start GMS.

1. Start GMS, or clear existing projects in GMS. If GMS is already running, select File | New. A new project can also be started by clicking New . 2. If necessary, register or update GMS. 1. Register GMS and components. Launch the GMS Registration Wizard. The option to register is given when opening an unregistered version of GMS. Use the Help | Register command to change registration options using the Aquaveo License Registration dialog. Follow the Registration Wizard instructions. Review the registered components in the Aquaveo License Registration dialog. 2. Update GMS. GMS can be updated by doing any of the following: Select Download if prompted to update when starting GMS. Select Help | Check For Updates. Go directly to the GMS download page. 3. Set the display projection. Select the Edit | Units... command. In the Units dialog, set the time, mass, force, and concentration. Click the button and set the horizontal and vertical projection in the Display Projection dialog. If necessary, use the Horizontal Projection dialog to set a global projection.

3. Create a SEEP2D project.
Start GMS, or a new project, in the GMS 2D program mode. Select SEEP2D and Profile line in the New Project dialog.

4. Create conceptual model features.
1. Create corner points. Right-click on the profile lines coverage and select the Attribute Table menu command. Enter point locations in the Attribute Table dialog. Points can be added using the Create Point/Node tool. Points can be edited using the Select Point/Node tool. 2. Create arcs. Use the Create Arc tool to connect points.

5. Assign materials.

1. Build polygons. Polygons are not created automatically when arcs are enclosed. To create polygons: Use the Feature Objects | Build Polygons command. 2. Define materials. Select the Edit | Materials menu command. Define SEEP2D materials in the SEEP2D tab of the Materials dialog. 3. Assign materials to polygons. Double-click on polygons using the Select Polygon tool. Assign materials using the Attribute Table dialog.

6. Define boundaries conditions.
Using the Select Arc tool or the Select Point/Node tool, double-click on a boundary condition arc or node. In the |Attributes Table dialog, assign the arc or node as either a specified head, exit face, or flow rate boundary condition.

7. Generate 2D mesh.

1. Redistribute vertices. 1. Manually add or remove vertices. Use the Create Vertex tool to add vertices along arcs. Use the Select Vertex tool to select vertices and delete them using the Delete key. 2. Use the redistribute vertices tool. Select arcs with the Select Arc tool. Select the Feature Objects | Redistribute Vertices menu command. Use the Redistribute Vertices dialog to add or remove vertices by changing the distribution. 2. Convert the SEEP2D coverage to a 2D mesh. Select the SEEP2D coverage in the Project Explorer. Select the Map to 2D Mesh macro.

8. Map conceptual model to the 2D mesh.
Select the conceptual model. Select Feature Objects | Map → SEEP2D. Select the appropriate options in the Map → Model dialog.

9. Set SEEP2D analysis options.
Select the SEEP2D | Analysis Options menu command. Set options in the SEEP2D Analysis Options dialog.

10. Run SEEP2D.
Save the project. Run SEEP2D

11. Review results.

1. Change display options. 1. Set display options. Open the Display Options dialog. Set the general display options. Set general lighting options. Set display options for each module that is being used. Set contour options. Set vector options. 2. View display. Use the Rotate , Pan , and Zoom tools. Use the View menu commands found in the Display menu. Use the Frame command to center and resize the display as needed. 3. Adjust display. Display may need to be adjusted during the remainder of the project. Use the Display Options dialog and viewing tools as needed. Use the Frame command to center and resize the display as needed. 2. Change contour options. Turn on Contours in the Display Options dialog and set contour options. The "Color Fill" option is recommended for this. Look for inconsistent points (points with values much higher/lower than their neighbors or regions where no data points exist). Verify that the region being modeled is covered by the elevation/depth data and there are no holes.
