The specific storage is the amount of water that a portion of an aquifer releases from storage, per unit mass or volume of the aquifer, per unit change in hydraulic head, while remaining fully saturated.

The groundwater transmission and storage properties of geologic formations including aquifers and confining units can be described by three hydrogeologic terms: transmissivity, T; specific storage, S s; and storativity, S.

2019年11月23日 · Specific storage is the volume of water that a unit volume of aquifer (or aquitard) releases from storage under a unit decline in head. Specific storage is related to the compressibilities of water and the aquifer (or aquitard) as follows: S s = ρ g α + n β

2020年2月1日 · Specific storage, which represents the aquifer’s capacity to release water from or take into storage when water level changes, is an important aquifer property required for transient groundwater modeling and water resources management.

Overall definition: Ss, specific storage, (1/L) of a saturated aquifer is the volume that a unit volume of aquifer released from storage for a unit decline in head. (Volume per Volume per head change). For a confined aquifer we must consider compressibility. How can a …

2023年9月26日 · This review synthesizes the existing methods published in the literature used to estimate the specific storage of aquitards. Specific storage data from 99 aquitards were collected, covering 11 types of aquitard material, including both unconsolidated deposits and rocks.

Adding the terms and multiplying by the factor ρ w g gives a specific storage of 2.3 × 10-4 m-1 and the ratio of sand-to-water compressibility is 3.5. Values of specific storage are dependent on rock type as well as variability within a lithology.

The specific storage is the amount of water that a portion of an aquifer releases from storage, per unit mass or volume of the aquifer, per unit change in hydraulic head, while remaining fully saturated.

Specific storage, which represents the aquifer's capacity to release water from or take into storage when water level changes, is an important aquifer property required for transient groundwater modeling and water resources management.

This review synthesizes the published literature on using different methods to estimate field specific storage of aquifers. The field methods include pumping tests, slug tests, and analyses of sea tides, atmospheric loading and earth tides, and seismic waves.
