Groundwater storage definition.
Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers. Groundwater is used for drinking water by more than 50 percent of the people in the United States, including almost everyone who lives in rural areas.
Vegetation storage – this is water taken up by vegetation. It is all the moisture in vegetation at any one time. Surface storage – the total volume of water held on the Earth’s surface in lakes, ponds and puddles. Groundwater storage – the storage of water underground in permeable rock strata.

Groundwater storage changes are rarely the dominant component of TWS variations on a seasonal basis, but they are often the dominant component on interannual to decadal timescales (Rodell and Famiglietti,2001;Lietal.,2015). Finally, the water stored in the form of snow or ice is the primary Following rainfall, variations in groundwater turbidity may be an indicator of surface contamination. Color. Can be caused by decaying leaves, plants, organic matter, copper, iron, and manganese, which may be objectionable. Indicative of large amounts of organic chemicals, inadequate treatment, and high disinfection demand.
Groundwater Resources. Groundwater is the water found beneath the Earth’s surface and occupies the very small cracks and spaces between rocks, gravel and sand. It is a common misconception that groundwater is in the form of underground lakes, streams and rivers, when in reality, groundwater is found inside rocks: in the small pore spaces ...
Groundwater Storage and the Water Cycle The ground stores huge amounts of water and it exists to some degree no matter where on Earth you are. Lucky for people, in many places the water exists in quantities and at depths that wells can be drilled into the water-bearing aquifers and withdrawn to server the many needs people have.For groundwater storage, Theis used the variable S, which he originally called the “specific yield” in the quote above and not to be confused with “specific yield” of an unconfined aquifer.
