The upstream and downstream boundaries of a river reach can be connected to a reservoir, lake, or other types of large water bodies. These water bodies are called storage areas. In GeoSTORM, the user can view and edit all the parameters of these storage areas in one editable data grid using the Storage Area Table Edit command. The user can also view the corresponding output results from this data grid.
Follow the steps below to use the Storage Area Table Edit command:
- From the Input ribbon menu, click the Storage Areas dropdown menu and select the Storage Area Table Edit command.
- The Storage Area Table Edit dialog box will be displayed.
The following sections describe how to use the Storage Area Table Edit command and interact with the above dialog box.
Selecting Storm Results
In the Select Storm Results section, the Storm result to display dropdown combo box allows the user to select the storm frequency whose result is to be displayed.
Note that the Select Storm Results section is available when either the Modified Rational, Rational Method, or DeKalb Rational Method is selected as the hydrology analysis engine in the Scenario Manager dialog box. Otherwise, this section is unavailable. Refer to this article in our knowledge base to learn more about the hydrology analysis engines supported by GeoSTORM.
Storage Area Parameters
The following panels are available in the Storage Area Parameters section:
- Storage Area Data
- Results Data
Storage Area Data
This panel contains editable data grid columns listing storage area parameters present in the current scenario.
The following storage area data parameters are provided in the data grid columns:
- Storage Area ID
This editable column lists all storage area IDs contained in the current scenario. Note that this editable column will also be available in the Results Data panel.
- Invert Elevation
This editable column lists the storage area invert elevations. The user can click the […] button to select the storage area invert elevation from the Map View.
- Initial WSEL
This editable column lists the water surface elevation of the storage areas at the start of the simulation.
Results Data
The data grid columns in this panel list corresponding output results for storage areas present in the current scenario.
The following storage area result parameters are provided in the data grid columns:
- Peak Inflow
This read-only column lists the peak flow rate that entered the storage area during the storm event.
- Peak Outflow
This read-only column lists the peak flow rate that leaves the storage area during the storm event.
- Peak Storage Volume
This read-only column lists the peak storage volume that occurred at the storage area during the storm event.
- Peak WSEL
This read-only column lists the peak water surface elevation that occurred at the storage area during the storm event.
- Peak Depth
This read-only column lists the peak water depth that occurred at the storage area during the storm event.
- Total Seepage Volume
This read-only column lists the volume of the water that has seeped out of the storage area during the entire storm event.
Sorting the Storage Area Table
The data in the Storage Area Parameters table can be sorted by multiple columns. The user can sort the data by holding down the [Shift] key while clicking the Up and Down arrows in the column headers. This allows for multi-column sorting without losing the previous sort. The sorting order is determined by the sequence in which the column headers are selected.
Follow the steps below to sort the data using multiple columns:
- Select the header of the first column and click the Up or Down arrow to sort the data in ascending or descending order.
- Hold down the [Shift] key, then select the header of the second column and click the Up or Down arrow to sort the second column.
- Repeat step 2 to sort the data of any additional column.
For example, first, select the Peak Inflow column and click the Up arrow to sort the data in ascending order. Then, while holding the [Shift] key, select the Peak WSEL column and click the Down arrow to apply a secondary sort.
Copying and Exporting Storage Area Parameters
The data in the Storage Area Parameters table can be copied to the clipboard or exported as a Microsoft Excel or PDF document by using the right-click context menu commands, such as Copy, Copy Table to Clipboard, Export Table to Excel, or Export Table to PDF.
After editing the required storage area parameters, click the [Close] button to close the Storage Area Table Edit dialog box.
