Everything about Specific Storage totally explained
Specific storage (S
s),
storativity (S),
specific yield (S
y) and
specific capacity are material physical properties that characterize the capacity of an
aquifer to release
groundwater from storage in response to a decline in
hydraulic head. For that reason they're sometimes referred to as "storage properties". In the field of
hydrogeology, these properties are often determined using some combination of field hydraulic tests (for example,
aquifer tests) and laboratory tests on aquifer material samples.
Specific storage
The
specific storage is the amount of water that a portion of an
aquifer releases from storage, per unit mass or volume of aquifer, per unit change in hydraulic head, while remaining fully saturated.
Mass specific storage is the mass of water than an
aquifer releases from storage, per mass of aquifer, per unit decline in hydraulic head:
