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]
A map released Tuesday in the journal Nature offers the first comprehensive map of the world’s underground water sources and the ecosystems that depend on them. In…
California aquifers, excerpted from map in Ground Water Atlas of the United States (USGS, 2000): Lavender is "other" for "rocks that generally yield less than 10 gal/min to wells"; dark green-blue (3) are the California coastal basin aquifers, bright-turquoise blue (7) is the Central Valley aquifer system, flat cobalt-blue (1) down south is Basin and Range aquifers
This data is displayed as series of interactive map layers in an easy to use map viewer format. Most layers in the North American Environmental Atlas are at a scale of 1:1:10,000,000 or finer. [citation needed] The variety of layers in the Atlas continues to expand in order to support analysis of environmental conditions.
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 CEC was established in 1994 by the member states of Canada, Mexico, and the United States to address regional environmental concerns under the North American Agreement on Environmental Cooperation (NAAEC), the environmental side accord to the North American Free Trade Agreement (NAFTA).
The Groundwater Atlas was compiled on a MediaWiki based platform, with the intention that the information could, at some point in the future, be migrated to Wikipedia. . Following discussions with Wikimedia UK, a selection of this text was licensed under a CC-BY-SA 3.0, compatible with Wik
According to Stanford Geophysics Professor Rosemary Knight, the empty space in our state’s groundwater aquifers is equal to the capacity of 30 Shasta Lakes. In addition to filling that space ...
