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]
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 ...
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. [1]
Some groundwater finds openings in the land surface and emerges as freshwater springs. In river valleys and floodplains, there is often continuous water exchange between surface water and ground water in the hyporheic zone. Over time, the water returns to the ocean, to continue the water cycle. The ocean plays a key role in the water cycle.
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 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 ...
