Critical groundwater supplies may never recover from drought
Let this sink in
“New UC Riverside research shows groundwater takes an average of three years to recover from drought — if it ever recovers at all. ”
“The researchers also suggest that farmers improve irrigation efficiency and switch perennials like almonds, pistachios, and walnuts to annual, less water-intensive crops in areas where groundwater depletion is severe.”
Isostatic rebound (often called glacial rebound, due to its most common cause) is the gradual lifting of a region of crust after mass resting on top of it is removed. It typically takes hundreds of years or more, depending how much and how fast the overburden was removed. Scandinavia, which is the most recent place to lose ice sheets, is continuing to rebound now. (This is why “sea level” on the Norwegian and Swedish coasts has been going down.)
So much net water mass has been lost from the California Central Valley aquifer and glaciers that the Sierra Nevada has risen 15cm over 150 years.
