Define Basin From Entered Data Dialog Box

Use this dialog box to define a basin for stage storage analysis, by entering contour level 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 Autodesk 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

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 level.

Add To Table

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