Aquifer Storativity

“How can we quantify the volume of water an aquifer is likely to release when there’s a change in head pressure?”

Wells pull water up from aquifers through pressure head reduction. But every aquifer is different, and we need to quantify how much water a formation is likely to release per pressure head reduction. Luckily, we have a parameter called Aquifer Storativity that measures the amount of water released per area to a given change in pressure head. For confined aquifers, storativity is equal to the specific storage times the aquifer thickness.
