Land Subsidence: We’ve Been Down This Road

The excellent Desert Sun-USA TODAY global groundwater depletion series brought a growing world problem to center stage. But it also sadly reminded me that ‘The more things change, the more they remain the same.’ We’ve been down this road before. To illustrate that, I’ll return to my hydrology graduate school days at the University of Arizona. There, I first learned of the water woes in the Texas portion of the Ogallala aquifer and the southern Central Valley aquifer system.
