Wetted Area

[VTHokie91]

Greetings.

I am consulting with a local company that stores and spreads biosolids. My survey crew did the field work on a storage lagoon and has provided me with contours. Using that information, I had no problem developing a stage-storage curve for the lagoon.

But the liner is nearing the end of its service life, and I've been asked to provide a square footage for the replacement. That's the total wetted area of the lagoon at its maximum elevation plus a bit for the berm top.

For the life of me I cannot find that information. I know that HydroCAD calculates it from other work with rain gardens, but I cannot find it.

Any advice will be appreciated.

Assuming that you entered stage-area data using the custom storage option, the surface area and wetted area are available on the Storage tab of the pond report.

Edit: When using custom storage you also have to select Pyramidal or Conic shape. The wetted area is undefined if you select the Prismatic (average-area) procedure.

Excellent, that did it. Thank you.
