The scientists analyzed how much water would be needed to recharge portions of aquifers that are driving the subsidence problems, and calculated it would be about 680,000 acre-feet per year on ...

Where subsidence is causing the most harm, we’ve got to try and get it to those compacting aquifers.” A section of the Friant-Kern Canal that was damaged by subsidence undergoes repairs in ...

California’s San Joaquin Valley may be sinking nearly an inch per year due to the over-pumping of groundwater supplies, with resource extraction outpacing natural recharge, a new study has found.

He was right. Greater Houston has some of the highest subsidence rates in the United States; within that region, parts of Katy are sinking faster than anywhere else, up to 1.4 centimeters a year ...

In San Diego, for example, the aquifers are so permeable that even small drops in water level lead to quick, large subsidence events. In Washington, D.C., by contrast, the bedrock is stiffer.

Temporal coverage of InSAR data, and the subsidence patterns they reveal, in the San Joaquin Valley. Credit: Communications Earth & Environment (2024). DOI: 10.1038/s43247-024-01778-w ...

The study cites the compaction of aquifers, a process in which the supply of water in an aquifer is withdrawn faster than it is recharged, as a leading cause of subsidence. Houston lies on top of ...

Subsidence, often called an "invisible threat," can damage infrastructure and increase flood risks. While some cities show slight uplift, it's negligible and doesn't negate the overall sinking trend.

But across the United States, urban areas are silently shifting: The land beneath them is sinking, a process known as subsidence, largely because people are using too much groundwater and aquifers ...

Aquifers In Crisis According to research published by the American Geophysical Union, the main cause of land subsidence in Iran is the excessive extraction of groundwater, with more than 90% drawn ...

The impacts of Resolution Copper's water use would be severe. And thanks to Arizona law, there's not much we can do about ...
