Specific storage in aquifers refers to how much water an aquifer can hold or release when water levels change. Scientists reviewed different methods to measure specific storage in aquifers, like pumping tests and analyzing tides and seismic waves. They found that specific storage values vary widely, with unconsolidated deposits having higher values than rocks. The hydraulic conductivity of aquifers shows more variation than specific storage, but there is a positive correlation between specific storage and porosity. Overall, specific storage is an important factor for understanding groundwater movement and managing water resources.
