Calculating Stage Storage Volumes from a Surface

Using the Stage Storage command, you can calculate incremental and cumulative volumes of a basin.

The storage volume at each depth (stage) is calculated from the input and the cumulative volume is totaled.

To define the basin, you can use one of the following:

• An existing surface.
• Selected contours within an existing surface.
• Existing polylines in the drawing. These must be lwpolylines, such as created with the PLINE command.
• Contour elevation and area data that you enter into a dialog box.

To use either a surface or contours within a surface, contours must be visible.
