= Specific storage
{wiki=Specific_storage}
Specific storage refers to the amount of water that can be stored in the pore spaces of geologic materials, such as soil or rock, that is available for extraction by gravity drainage. It is a measure of the water that can be retained in the pore spaces after the water table has been lowered and is typically expressed as a ratio or percentage. Specific storage is an important concept in hydrogeology and groundwater management, as it helps to quantify how much water can be stored and potentially withdrawn from aquifers.
