HydroGeoSphere Basic Workflow

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:

Expand1. Start GMS.

Expand1. 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 . Expand2. If necessary, register or update GMS. Expand1. 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. Expand2. 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. Expand3. 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.

Expand2. Import data.

Expand1. Gather and open image files. Images are imported into the GIS module in GMS. Expand1. 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. Expand2. Import images from the web. Use the Add Online Maps macro. Select a location in the Virtual Earth Map Locator. If a projection has not been set for the project, set a new project in the Display Projection dialog. Use the Data Service Options dialog to select a web service. Expand2. Gather and open geometric data files. Expand1. Import map data. Use the File | Open... command to import map data such as Map files, boundary ID files, or boundary XY files. Alternately, drag and drop the file into the Graphics Window in GMS. Expand2. Import GIS data. Use the File | Open... command to import GIS data files such as Shapefiles or raster files. Alternatively, drag and drop the file into the Graphics Window in GMS. Expand3. Import scatter data. Use File | Open... to open files with scatter data. Alternatively, drag and drop the file into the Graphics Window in GMS. Use the File Import Wizard to specify how to import the data. Expand4. 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. Expand5. Review and set object projections. Right-click on an object in the Project Explorer and select the Projection | Projection command. Set the horizontal and vertical projection using the Object Projection dialog. To set a global projection, use the Horizontal Projection dialog. Expand3. 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.

Expand3. Create a UGrid.

Create a 3D UGrid in one of the following ways: Expand1. 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. Expand2. 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.

Expand4. Create a HydroGeoSphere simulation.
Right-click in the Project Explorer and select the New Simulation | HydroGeoSphere command.

Expand10. Map from the coverages to the MODFLOW 6 packages.
For each of the packages that can be mapped from coverages: In the Project Explorer, right-click on the package and use the Map from Coverage command. Select the desired coverage from the Select Coverage dialog to map its data to the selected package.

Expand11. Set up additional package parameters.
As desired, modify the package parameters: Set up global and output package parameters: TDIS, IMS, DIS, IC, OC. Set up flow package parameters: NPF, HFB, GNC. Set up optional package parameters, including boundary conditions such as: CHD, GHB, RIV, SFR, etc.

Expand12. Run HydroGeoSphere.
In the Project Explorer, right-click on the MODFLOW 6 simulation and Save Simulation and Run. The Simulation Run Queue dialog will appear; allow the simulation to run to completion. When the simulation has finished successfully, click Load Solution.

Expand13. Visualize the solution.

Expand1. Change display options. Expand1. 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. Expand2. 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. Expand3. 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. Expand2. 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. Expand3. Create a plot. If a PEST Observations package was included with the model, do the following to visualize the results: Under the " Map Data", find the coverages labelled with PEST. Click on them to visualize whisker plots in the Graphics Window. Right-click on a coverage and use the Observations command to view plots related to the data in the coverages in the Observations dialog. Expand4. Create an animation. Select a solution dataset and use the Display | Animate menu command. Use the Animation Wizard to specify the animation parameters. Save and view the animation file. Expand5. Visualize water budgets. Expand1. Visualize the VOLUME BUDGET section of the text solution file. Double-click on a text file under the MODFLOW 6 solution folder in the Project Explorer. It might end in ".lst" or ".out". Scroll to the bottom of the file to the VOLUME BUDGET section, and review the values. Expand2. Run ZONEBUDGET and visualize the results. Expand1. Create the Zones package. Use the New Package | Zones command to open the Zone File dialog. Using the Zone File dialog, define the zones. Right-click on the MODFLOW 6 simulation and select Save Simulation to export the zone package file. Expand2. Run ZONEBUDGET. Under the MODFLOW solution folder in the Project Explorer, right-click on the file ending in ".cbc" and select Run ZONEBUDGET. Expand3. Visualize the results of ZONEBUDGET. Under the folder ending in "zone_budget", double-click on either file to open it in an outside program. The file ending in ".lst" has the results of ZONEBUDGET at the bottom under a section that begins VOLUME BUDGET. The file ending in ".csv" can be opened in a spreadsheet application or text editor.
