Define Basin From Entered Data Dialog Box

Use this dialog box to define a basin for stage storage analysis, by entering contour elevation and area data.

This dialog box enables you to enter data for contours that may not be available in digital format. If you have an AutoCAD Civil 3D drawing with a surface or polylines, you may wish to use the Define Basin From Entities dialog box instead.

This dialog box is accessed from the Stage Storage dialog box.

Enter Contour Elevation Data

Note: Only numeric values are accepted in these fields. The units are based on the Drawing Units specified on the Units And Zone tab of the Drawing Settings dialog box.
Contour Elevation

Specifies the elevation for the contours that represent the basin elevations. You can enter the contours in any elevational order. When you click Add To Table, the data is sorted from lowest to highest elevations in the Stage Storage dialog box.

Note: You can press TAB to move to the next field in the dialog box.
Contour Area

Specifies the area for the contour that exists at the specified elevation.

Add To Table

Adds the specified data to the table in the Stage Storage dialog box.

Note: If needed, you can return to the Define Basin From Entered Data dialog box, add more contour data, and add it to the table.
