Natural Floodplains Are Quickly Vanishing
From 1992 to 2019, 600,000 square kilometers of natural floodplains were lost globally due to land conversion.
Seismometers Listening at Rivers to Measure Sediment Transport
Bedload sediment, transported throughout an alpine catchment by a flood, was remotely tracked in detail by analyzing the ground vibrations recorded by a network of 24 seismic sensors.
Farming Is Intensifying Floods in the South American Plains
The replacement of native vegetation by crops has raised groundwater levels in the Pampas, a new study suggests.
Specious Timescales from Sedimentary Layers
Changing environments can dramatically change how quickly layers form in sedimentary rocks, leading to incorrect time estimates.
Unlocking the Secrets of Floods: Breakthroughs in Riverine and Coastal Modeling
To enhance flood modeling, it is imperative to gain a comprehensive understanding of the causative mechanisms and cutting-edge models and tools, while also acknowledging their uncertainties.
Forecasting Earthquake-Induced Floods
Surface-rupturing earthquakes can abruptly reroute rivers when fault scarps function like dams. Researchers have now successfully modeled such an event that occurred in New Zealand.
GPS Observations Sense Groundwater Change in Australia
By exploiting the fact that changes in groundwater cause deformations of the Earth’s surface, GPS receivers are used to detect groundwater changes related to extreme events and to seasonal oscillations.
A Turning Point for Estuaries Worldwide
As estuarine barriers are built in response to sea level rise, flooding, and salinization, more research is needed to better understand their implications for human activities and ecosystems.
Back-to-Back Hurricanes Could Become Common by 2100
New research shows back-to-back hurricanes could strike the United States every few years by 2100.
