A Shift in Groundwater Perspective

When it comes to natural disasters, the sudden, swift devastation of landslides, mudslides, and sinkholes may get all the attention — but natural resource scientists can attest that it’s the slow sinking of the ground surface that is just as real a danger. “Subsidence often gets neglected because it is slow moving. You don’t recognize it until you start seeing damage,” says Michelle Sneed, a land subsidence specialist at the United States Geological Survey (USGS).

Researchers Use Satellite Imaging to Map Groundwater Use In California’s Central Valley

Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California’s San Joaquin Valley.
