ground water flow into detention pond
ground water flow into detention pond
(OP)
I am working of a design where the detention pond normal water elevation is lower than the groundwater table and would like some advise on the best way to compute the amount of groundwater that will enter the pond. The water tabel is about 3 feet higher that the normal water level in the pond

If I remember correctly from my college curriculum, a pond will 'daylight' at the same elevation as the water table. There will be a drawdown effect, that is to say, being that your groundwater will have a place to drain, pond levels will be higher leaving you with less water in the surrounding land ie. a slightly lower water table.
I have seen equations for calculating the water level in a well that demonstrates the same effect, only on a smaller scale. It's possible a modified model would apply. If I find any applicable data, I'll let you know.
