Indications for Protracted Groundwater Depletion after Drought over the Central Valley of California


Wang, S-Y Simon; Lin, Yen-Heng; Gillies, Robert R; Hakala, Kirsti (2016). Indications for Protracted Groundwater Depletion after Drought over the Central Valley of California. Journal of Hydrometeorology:1-9.

Abstract

Ongoing (2014–15) drought in the state of California has played a major role in the depletion of groundwater. Within California’s Central Valley, home to one of the world’s most productive agricultural regions, drought and increased groundwater depletion occurs almost hand in hand, but this relationship appears to have changed over the last decade. Data derived from 497 wells have revealed a continued depletion of groundwater lasting a full year after drought, a phenomenon that was not observed in earlier records before the twenty-first century. Possible causes include 1) lengthening of drought associated with amplification in the 4–6-yr drought frequency since the late 1990s and 2) intensification of drought and increased pumping that enhances depletion. Altogether, the implication is that groundwater storage in the Central Valley will likely continue to diminish even further in 2016, regardless of the drought status.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
