That Sinking Feeling: Valley Land Subsidence Poses Problems for Water, High Speed Rail
The U.S. Geological Survey has recently released a study showing that large groundwater withdrawals are causing subsidence in California’s Central Valley, leading to concerns over California's proposed high speed rail system. Bruce Kutter, a civil engineering professor at UC Davis, says the integrity of the rail bed will depend on the severity of the subsidence and how rapidly it occurs along the track.
