Researchers at the University of California, San Diego (UC San Diego) are deploying remote sensing technology called InSAR to gain insights into sustainable groundwater in the San Joaquin Valley. The satellite-based InSAR (for “interferometric synthetic aperture radar”) creates high-resolution maps of land surface motion in space and time, including subsidence measurements (measurement of sinking). InSAR and the fine-scale resolution images it delivers are useful in evaluating subsidence patterns and habits according to crop type.
Subsidence can occur when large quantities of groundwater are removed from underground stores. It influences the ability to monitor and manage groundwater in agricultural regions, like the San…READ MORE
