Rising Groundwater Threatens Inland Flooding in Coastal Cities

Breaking News, Climate Actions, Environment

Rising sea levels caused by climate change are bringing an often-overlooked threat to coastal communities rising groundwater. While coastal erosion and storm surges have been widely studied, the inland spread of flood hazards due to groundwater rise remains a hidden danger. A recent study by Cox et al. focuses on Dunedin, New Zealand, a city already facing periodic flooding, and presents a method to predict how rising seas will impact groundwater levels, offering crucial insights for flood risk management. The research, based on data from 2019 to 2023 collected from 35 groundwater sensors, shows that as sea levels rise, groundwater levels will also increase, limiting the land’s ability to absorb rainfall and leading to higher risks of surface flooding. Even before reaching the surfac...
