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). [6]
Ecosystems around the world are at risk from declining levels of underground water, a study has found — and protected areas aren’t growing fast enough to stem the losses. A map released ...
The San Joaquin Valley recently received some good news about its groundwater: We are replenishing more of it whenever we have the chance. Comparing two recent wet years — 2017 to 2023 — the ...
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 ...
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.
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 South Wales. It is 3000 metres (9800 feet) deep in places and is estimated to contain 64,900 cubic kilometres (15,600 cubic miles) of groundwater. [4]
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer .
Water security in Australia became a major concern in Australia in the late 20th and early 21st century as a result of population growth, recurring severe droughts, effects of climate change on Australia, environmental degradation from reduced environmental flows, competition between competing interests such as grazing, irrigation and urban water supplies, and competition between upstream and ...
