Phys.org April 15, 2024 Sea-level rise (SLR) is influencing coastal groundwater by both elevating the water table and shifting salinity profiles landward, making the subsurface increasingly corrosive. Low-lying coastal municipalities worldwide are vulnerable to an array of impacts spurred by these phenomena, which can occur decades before SLR-induced surface inundation. Damage is accumulating across a variety of infrastructure networks that extend partially and fully beneath the ground surface and it is largely overlooked as part of infrastructure management and planning. Researchers at the University of Hawaii provided an overview of SLR-influenced coastal groundwater and related processes that have the potential […]

Scientists map loss of groundwater storage around the world
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 […]
