Problem

In PondPack, where do I find pond results like Elevation vs. Volume? For example if I'm using a Pipe or trapezoidal pond volume type and want to see the equivalent elevation-volume or elevation-area curve.

Solution

In PondPack V8i and CONNECT Edition (2009+), after computing the model, this information is available by right-clicking on the Pond and selecting Pond Volume Results Table. So for example you could find the elevation-volume table for a Pipe pond.

If you would like to see more data points (rows), add more rows to the pond's elevation-area or elevation-volume curve.

You can also find this information in Report Builder under the report section "Pond Volumes".

In PondPack 10 (circa 2005-2008), you could double click on the pond, click the Graph tab and would have the option of generating a pond storage or pond volume graph and table.

Note that when using the elevation-area method for a pond, PondPack uses the conic method to compute the incremental volume between pond contours. The incremental volumes are then summed to create a volume rating table of cumulative pond volumes. PondPack uses the following equation to calculate the incremental volume between two points on the user-defined elevation versus area curve.

Where:

E1 = Bottom contour elevation of incremental volume
E2 = Top contour elevation of incremental volume
A1 = Surface area at E1
A2 = Surface area at E2
DV = Volume between areas 1 and 2
