With views stretching off to the horizon, it's hard to visualize the San Joaquin Valley sinking--unless, of course, you have a measuring stick about the size of a telephone pole. This has profound implications for water management in California.
In a newly released study, the Stanford team combines satellite data from multiple decades with readings from ground-based GPS stations, resulting in a kind of three-dimensional map pinpointing areas most affected by over-pumping.
What we've shown in this study is that, well, it's not just something from the past. It's happening now and what's more, it's faster than it has been, faster than it was before.
The goal is to identify super porous basins and farmland that could be flooded or pumped with diverted water to recharge the sinking aquifers, indicating a potential solution.
