This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality.

Approximately 85% of water used in California by farmers and residents today is from groundwater, with 6 million Californians relying solely on this resource. [2] The Central Valley is a big user of groundwater for agricultural purposes which supplies a large portion of food for not only California, but for the rest of the United States as well. [3]
GMS (Groundwater Modeling System) is water modeling application for building and simulating groundwater models from Aquaveo. It features 2D and 3D geostatistics , stratigraphic modeling and a unique conceptual model approach.
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
Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
The latest drought, from 2020 through 2022, set a record as California’s driest three-year period on record, and state data show more than 2,600 dry wells were reported during that time.
[3] [4] As a result, investment into groundwater recharge basins has been steadily increasing in recent years. Groundwater projects are planned to provide an increase of 500,000 acre-feet annually to the water supply. [5] With 2023 being an extreme wet year, California achieved a record-setting 8.7 million acre-feet of groundwater to aquifers. [6]
An example of a non-discretized radial model is the description of groundwater flow moving radially towards a deep well in a network of wells from which water is abstracted. [7] The radial flow passes through a vertical, cylindrical, cross-section representing the hydraulic equipotential of which the surface diminishes in the direction of the ...
