Increasing threat of coastal groundwater hazards from sea-level rise in California

Nature Climate Change, Published online: 17 August 2020; doi:10.1038/s41558-020-0874-1

Sea-level rise raises water tables, causing flooding from below and saltwater intrusion. A modelling study predicts that coastal California groundwater flooding will expand 50–130 m inland with 1 m of sea-level rise, with areal flooding extent strongly dependent on topography and drainage capacity.
