Storage Coefficient (S)

Top Previous Next


The volume of water an aquifer releases from or takes into storage per unit surface area of the aquifer per unit change in head.


It is a volume of water per volume of aquifer released as a result of a change in head. For a confined aquifer, the storage coefficient is equal to the product of the specific storage and aquifer thickness.

Why is storage coefficient important?

This is a measure of the volume of water stored and released in an aquifer and is used to quantify the safe yield of an aquifer system.
