Going Down: How Do Cities Carry That Weight?
Calculations show that the added weight of growing cities can lead to tens of millimeters of subsidence, an effect that needs to be considered for coastal cities under threat by sea-level rise.

Machine Learning Predicts Subsidence from Groundwater Pumping
Machine learning and data on aquifer type, sediment thickness, and proxies for irrigation water use has been used to produce the most comprehensive map of land subsidence in the western U.S. to date.

Global Risks and Research Priorities for Coastal Subsidence
Some of the world's largest cities are sinking faster than the oceans are rising. Humans are part of the problem, but we can also be part of the solution through monitoring and modeling.
