area | the basin horizontal area in square feet |
elevation | the elevation in feet at which this area is measured. |
As shown above, contour areas are the horizontal area at a specific vertical elevation. The program computes a volume from the contour areas by use of the prismoidal formula. For basins which use storage pipes, a master list of contour areas will be generated for use in the routing computation. The output summary will give a running total of basin volumes next to the areas.
