This is a top level workflow. This workflow includes all of the specific workflows needed in creating a general FEMWATER flow model project using the conceptual model approach. Newer and infrequent GMS users should start here.
To build a FEMWATER flow model in GMS, use the following steps:
| 1. 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.
- 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.
|
|
|
| 2. Import data.
|
| 1. Gather and open image files.
|
Images are imported into the GIS module in GMS.
| 1. Open local images.
|
- Load images from local computer files using the File | Open... command.
- Alternatively, drag and drop the file into the Graphics Window in GMS.
|
|
| 2. Gather and open geometric data files.
|
| 4. Import CAD data.
|
- Verify the CAD file type is readable by GMS before importing it. GMS can import DXF and DWG files.
- Use the File | Open... command to launch the Open dialog (or drag and drop) to import the CAD files.
- The data should load in layers into the Project Explorer.
|
|
| 3. Gather hydrologic data files.
|
- Gather data files for hydrologic and hydraulic data. These include data such as hydrographs, water levels, and rating curves. They will be imported when setting boundary conditions and when doing model calibration.
|
|
| 3. Define the project boundaries.
|
| 1. Create a new conceptual model in the Project Explorer.
|
- Create a new conceptual model with the "FEMWATER" type.
| 2. Add coverages.
|
| 1. Create new coverage from scratch.
|
- Use the New Coverage right-click command.
- Use the Coverage Setup dialog to create a new coverage by selecting the desired coverage properties and naming the coverage.
|
| 2. Create new coverage from an existing coverage.
|
- Use the Duplicate command on an existing coverage. This will copy any feature objects on the coverage.
- Use the Rename command to give the coverage a new name.
- Change the coverage setup.
|
|
|
| 2. Create the boundary arcs.
|
| 1. Create feature points, arcs, nodes and vertices.
|
- In the map module, create feature objects in the active coverage.
- Use the Create Arc
 tool to create arcs in the map coverage.
- Begin creating a new arc by clicking in the graphics window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
- Double-click or press the Enter key to terminate the arc.
- Use the Create Point
 tool to create additional nodes alone or to split arcs.
|
| 2. Modify arcs.
|
- Feature arcs, whether digitized or incorporated from a boundary condition or a material coverage, often need to be edited after initial creation.
| 1. Create additional vertices on arcs.
|
- Use the Create Vertex
 tool to add vertices along arcs.
|
| 3. Split arcs.
|
- An existing arc can be split by:
| 2. Add a node to the arc.
|
- Use the Create Point tool to add a node on an arc in order to split it into two arcs.
|
| 3. Connect the end of an existing arc to the middle of the arc.
|
- Use the Select Points\Nodes
 tool to drag the node of an existing arc to anywhere in the middle of another arc. This will split the second arc into two arcs.
|
| 4. Add a new connecting arc.
|
- Use the Create Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
|
|
|
| 4. Define boundary conditions.
|
| 1. Assign boundary conditions to arcs.
|
- Using Select Arc
 tool, right-click on the arc and select the Attributes Table command.
- Define the boundary condition properties in the Attributes Table dialog.
|
| 2. Assign boundary conditions to nodes.
|
- Using the Select Point/Node tool, right-click on the node and select the Attributes Table command.
- Define the boundary condition properties in the Attributes Table dialog.
|
|
| 5. Assign recharge values.
|
- Using the Select Polygon
 tool, double-click on the recharge polygon.
- Assign recharge properties in the Attributes Table dialog.
|
| 6. Create wells.
|
| 1. Create wells points.
|
- Create feature points in the well location.
| 1. Create feature points, arcs, nodes and vertices.
|
- In the map module, create feature objects in the active coverage.
- Use the Create Arc tool to create arcs in the map coverage.
- Begin creating a new arc by clicking in the graphics window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
- Double-click or press the Enter key to terminate the arc.
- Use the Create Point tool to create additional nodes alone or to split arcs.
|

|
| 2. Interpolate elevation data to TINs.
|

- Use the View menu commands found in the Display menu.
- Use the Frame
 command to center and resize the display as needed.

- 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.
|
| 3. Create a plot.
|
| 2. Select available plot type.
