Summary

Description
English: Chart showing loss / depletion of groundwater in the Central Valley of California
  • Source: Liu, Pang-Wei; Famiglietti, James S.; Purdy, Adam J.; Adams, Kyra H.; McEvoy, Avery L.; Reager, John T.; Bindlish, Rajat; Wiese, David N.; David, Cédric H.; Rodell, Matthew. (19 December 2022). "Groundwater depletion in California’s Central Valley accelerates during megadrought". Nature Communications 13 (7825). DOI:10.1038/s41467-022-35582-x.
  • Archive of source chart itself.
  • Source states: "Fig. 4 shows that the periods for groundwater recovery were shorter, and mostly driven by extreme weather events. ... (T)hese extreme wet events typically generated flooding, and had significant negative social, environmental and economic consequences."
  • Source describes the Fig. 4: "Groundwater losses combining the USGS’s Central Valley Hydrologic Model (CVHM)13 and the GRACE/FO estimates since 1962. The black line represents the overall groundwater depletion from 1962 to 2021 calculated by combining the CVHM and GRACE estimates."
  • Technical note: the SVG code for the grid and legends was automatically generated by the "Line charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG. Uploader used Inkscape to "trace" a version of the source chart, and inserted the resulting paths to form the final SVG file. Minor additions and adjustments were made in a text editor.
