Impacts by Moving Gravel Cause River Channels to Widen or Narrow
A new analytical model describes how the amount and grain size of sediment transported by rivers influences bedrock channel width, which can be used to predict where rivers will widen or narrow.

The Wildfire One-Two: First the Burn, Then the Landslides
Severe wildfires strip away plant cover and reduce the soil’s ability to hold water. A new study develops a model to better understand landslide risk following a burn.

Thickness and Strength of Slow-moving Landslides Revealed
Hundreds of slow-moving landslides’ deformation patterns were inverted to obtain their thickness and frictional strength, revealing that larger landslides are weaker and thinner than smaller ones.

Predicting the Next Big Frost Quake
Frost quakes occur in boreal regions when rapidly expanding ice underground causes frozen soils to fracture. A recent frost quake in Finland has given scientists a rare look into how they form.

Experimenting with Underwater Sediment Slides
Sediment-laden currents caused by breaching flow slides are hazardous to flood defenses and seabed infrastructure. New research shows that these phenomena must be accounted for in erosion simulations.

How River Capture Affects the Evolution of Aquatic Organisms
River basins are dynamic environments that are always changing and reorganizing under geologic forces. New research investigates how this shape shifting influences aquatic speciation and extinction.
