Detention Pond Volume
Detention Pond Volume
(OP)
Can someone give me an equation I can plug into excell to calculate the volume/capacity of an irregular shaped detention pond with sloped sides, assuming the top and bottom areas are known?

0.5 * (Upper Area + Lower Area) * (Upper Elevation - Lower Elevation).

Thanks also amb2002. I compared the two equations, and the results were almost identical.

If the shape of the basin is irregular, you can get closer to the actual number by measuring the area at various elevations and performing additional computations.
The smaller your vertical increment is, the more computations you'll do, and the more accurate the final number will be.

I used to perform dam breach analsyses and predicted 2 such later events within .5 ft of the actual flood level. Luckily my calculations were .5 ft higher than the occurrence.
Always remember we engineers work on averages, head in the oven, feet in the freezer, crotch is warm....
Also, you are measuring this with a micrometer, but cutting it with a chainsaw!!!!! Just because we have 5 digits right of the decimal does not mean we have to look further than the first one.
