How Groundwater Depletion Drives Land Subsidence in Coastal Delta Cities

Quick fact

In many coastal deltas, land subsidence from groundwater pumping can exceed sea-level rise by several centimeters per year, making the ground itself the biggest contributor to relative sea-level increase.

Why this is interesting

The ground beneath your feet slowly sinks every year. In some coastal cities, the land is dropping faster than the sea is rising.
