Revision as of 21:54, 5 January 2024
This is a top level workflow. This workflow includes all of the specific workflows needed in creating a general HydroGeoSphere project. Newer and infrequent GMS users should start here.
To build a HydroGeoSphere 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. Create UGrids (both 3D and 2D).
|
HGS will require both a 3D UGrid and a 2D UGrid
- Create a 3D UGrid in one of the following ways:
1. Create a 3D UGrid from scratch.
|
- Right-click in the Project Explorer and select New | UGrid 3D....
- In the New UGrid dialog, enter the information for the X-, Y-, and Z-Dimension of the grid.
|
2. Create a 3D UGrid from a coverage.
|
- Right-click on the desired coverage and select the Map To | UGrid command.
- In the Map → UGrid dialog, set the Dimension drop-down to "3D".
- Enter the rest of the information for the grid, including the X-, Y-, and Z-Dimension information.
|
|
5. Set the HydroGeoSphere Simulation Control.
|
- Right-click on the HydroGeoSphere simulation in the Project Explorer and select the Simulation Control command.
- Define the simulation parameters in the HGS [[ |Simulation Control]] dialog, including:
- General parameters
- Units
- Saturated flow
- Variably saturated flow
- Time stepping
- Output
- Zones
- Initial conditions
|
6. Define HydroGeoSphere zones.
|
1. Create zones from a raster.
|
- Import raster data.
- Create a cell-based dataset on a 3D UGrid by right-clicking on the UGrid and selecting the Z Values → Cell Dataset command.
- Interpolate the raster data to the 3D UGrid by right-clicking on the raster and selecting the Interpolate → UGrid command.
- Use the Interpolate Priority Rasters tool to define how the raster data is interpolated to the UGrid. Values from the raster will define the zones.
|
2. Create zones from a coverage.
|
1. Create coverage for defining zones.
|
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 polygons that define the zones.
|
1. Create enclosed arcs for polygon areas.
|
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.
|
|
|
|
2. Build polygons in enclosed areas.
|
- Polygons are not created automatically when arcs are enclosed. To create polygons:
- Use the Feature Objects | Build Polygons command.
|
|
3. Use the polygon to define zones on the UGrid.
|
- Select and make active a dataset on the UGrid which will define the zones in the simulation run. Make certain to be in plan view and shows the correct layer.
- Select the coverage containing the zone polygons.
- Select a polygon then right-click and select the Select Intersecting Objects command.
- In the Select Objects of Type dialog, select the UGrid.
- With the cells selected on the UGrid, change to cell values (S) to define the zone.
|
|
|
