Phys.org  November 6, 2023 Groundwater overdraft gives rise to multiple adverse impacts including land subsidence and permanent groundwater storage loss. Existing methods are unable to characterize groundwater storage loss at the global scale with sufficient resolution to be relevant for local studies. A team of researchers in the US (Colorado State University, Missouri University of Science and Technology, Desert Research Institute) explored the interrelation between groundwater stress, aquifer depletion, and land subsidence using remote sensing and model-based datasets with a machine learning approach. They developed a model which predicted global land subsidence magnitude at high spatial resolution (~2 km), provided a […]
