Researchers say knowing how much water is being extracted is crucial for addressing infrastructure and water supply crises in the capital.
Tracking Subsidence on Deltas With Fiber-Optics
Fiberoptic strain meters capable of measuring micron-scale subsidence reveal a Holocene sediment package on the Mississippi Delta that is mostly stable.
Projection: $110 Billion in Repairs for Russian Pipelines on Permafrost
Permafrost thaw is a major threat to pipelines in the Russian Arctic, particularly those carrying natural gas.
Forecasting Compound Floods in Complex Coastal Regions
Coastal communities face more frequent floods in which rain, rivers, and ocean storm surge combine forces. A reliable system that accurately predicts inundation from these events is urgently needed.
For Venice’s Floodgates to Work, Better Forecasts Are Needed
Climate change increases massive storm surges, which may be more than Venice’s flood-control system can handle.
SE Asia Peatlands Subsidence Tied to Drainage Density
Human-made channelization significantly accelerates peat decomposition and drives ground-surface deformation in tropical wetlands.
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.
Pumping Offshore Groundwater Resources Has Consequences on Land
While vast volumes of fresh groundwater are located offshore, pumping these reserves can also deplete on-shore aquifers and cause land subsidence.
Fiber Optics Opens Window into Subsurface Deformation
The distributed deformation of buried materials is difficult to map, but a new approach is able to resolve vertical deformation over the length of a fiber optic cable.
