An ecosystem can be directly or indirectly dependent, [7] as well as have a variation in groundwater use throughout the seasons. [1] There are a variety of methods for classifying types of groundwater-dependent ecosystems either by their geomorphological setting and/or by their respective groundwater flow mechanism (deep or shallow).

This is an accepted version of this page This is the latest accepted revision, reviewed on 29 January 2025. Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
California is the only state with a groundwater law that includes provisions intended to protect groundwater-dependent ecosystems. But the law, adopted in 2014, gives considerable leeway to local ...
According to Groundwater, by Freeze and Cherry (1979), specific storage, [m −1], of a saturated aquifer is defined as the volume of water that a unit volume of the aquifer releases from storage under a unit decline in hydraulic head.
While there is the potential for expanded groundwater use, because so little is known about groundwater-dependent water bodies and ecosystems any expanded groundwater use is suspended. [18] Dependent ecosystems include freshwater and estuarine wetlands, mangrove and paperbark communities, and surface-water fauna.
Lake Gnangara is fed by ground water of the Gnangara Mound. The Gnangara Mound is an area north of Perth, Western Australia where a large mound of sandy soil reaches an elevation of about 60 metres (200 ft). It stores about 20 cubic kilometres (710 billion cubic feet) of fresh water, about one hundred times Perth's current annual water usage.
The hyporheic zone is the region of sediment and porous space beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water.The flow dynamics and behavior in this zone (termed hyporheic flow or underflow) is recognized to be important for surface water/groundwater interactions, as well as fish spawning, among other processes.

Measured water temperatures range from 30 to 100 °C (86 to 212 °F). The basin provides the only source of fresh water through much of inland Australia. [2] The basin underlies 22% of the Australian continent, [3] including most of Queensland, the south-east corner of the Northern Territory, north-eastern South Australia, and northern New ...
