Scotland’s Last Glaciers Cause a Shift in an Old Paradigm

by Olga Sergienko 24 March 202324 March 2023

Cosmogenic geochronology of Scotland’s vanished glaciers indicates that the paradigm of weakened North Atlantic currents causing a rapid regional cooling is no longer valid.

Artificial Lake-Level Lowering Alleviates Floods in the Himalayas

by Dongfeng Li 8 March 20236 March 2023

A new model combining future permafrost degradation and related avalanches demonstrates that artificial lake-lowering could significantly reduce the risk of glacial lake outburst floods.

When Projecting Coastal Resilience, Sediment Compaction Is Key

by Morgan Rehnberg 30 September 202230 September 2022

The addition of new sediment helps build up lowland environments like deltas and marshes, but it also compacts materials beneath it—a vital, but often overlooked, factor in landscape evolution studies.

Tracking Subsidence on Deltas With Fiber-Optics

by John Shaw 20 September 202219 September 2023

Fiberoptic strain meters capable of measuring micron-scale subsidence reveal a Holocene sediment package on the Mississippi Delta that is mostly stable.

Can We Better Predict Coastal Change?

by Jaap Nienhuis, Florent Grasso, Evan B. Goldstein, Robert Kopp, Kristen Splinter and Kristy Tiampo 17 June 20221 August 2022

A new special collection invites studies on a new era of models and knowledge that provide predictions or insights into predictability in coastal geomorphology.

Good or Bad Jam? Modeling Boulders’ Fate at Constrictions

by Mikaël Attal 23 May 202215 November 2022

A new modeling framework to assess the likelihood of jamming at constrictions can be used to support the design of effective mitigation measures and reduce risk in debris flow prone areas.

Running Water on Topographic Data to Better Delineate Channels

by Mikaël Attal 25 April 202227 April 2022

Two-dimensional hydraulic simulations are a powerful tool to identify process domains such as channels, hillslopes, and floodplains in high-resolution topographic data.
