Adding Elevation vs. Area Data to a Pond
You can add an elevation-area curve to a pond. The area-elevation points defined in the curve are used to calculate pond volumes. You define elevation-area curves in the Elevation-Area Curve dialog box.
To add an Elevation vs. Area curve to a pond:
- Click a pond in your model to display the Property Editor, or right-click a pond and select Properties from the shortcut menu.
- In the Physical section of the Property Editor, select Elevation-Area Curve in the Volume Type field. The Elevation-Area Curve field becomes available.
- Click the Ellipses (...) button next to the Elevation-Area Curve field.
- In the Elevation-Area Curve dialog box, each row in the table represents a point on the Elevation-Area curve. Type values for Elevation, Area, and Percent Void Space for each row. Click the New button to add a row or press the Tab key to advance to the next field in the table.
- Perform the following optional steps:
- To delete a row from the table, select the row then click Delete.
- To view a report on the curve, click Report.
- To view a plot of the curve, click Graph.
- Click OK to close the dialog box and save your curve data in the Property Editor.
Elevation-Area Curve Dialog Box
This dialog box allows you to define elevation-area curves.
The dialog box contains the elevation-area table and the following buttons:
The table contains the following columns:
Column | Description |
---|---|
Elevation | The elevation data for the pond. |
Area | The plan area at that elevation. |
Percent Void Space | The void space volume data for the pond. Void space is used on any volumes option to adjust the effective storage volume for rock-filled or other porous media filled basins or vaults. Set this to 100% if there are no rocks or fill to reduce the available volume. |
