Congratulations to Dr. Alessandro Ielpi for his recent publication in the Nature Geoscience Journal titled "A tenfold slowdown in river meander migration driven by plant life"
View media coverage and interviews with Dr. Ielpi below.
Physics Today: Plants slow river migration
"The findings suggest that slower migration caused by land plants enhances soil carbon storage: The more vegetation there is along a river’s edge, the longer the river takes to shift position and shape. As a result, vegetated rivers promote carbon storage—and eventual capture—in the soil. In contrast, unvegetated rivers expose buried carbon more frequently and release carbon dioxide into the atmosphere. Similar analyses could help to extrapolate the migration rates of ancient, large, unvegetated channels on Earth and Mars and thus provide insights into past landscapes and environments."

"Meandering rivers may hold a vital clue to the earth’s capacity for life"
CBC Morning North: Broadcast radio interview.
"New research shows that a river will change shape relative to the amount of plant life along its banks. That can be useful information when it comes to planning in relation to climate change."
Montreal Times: New research from Laurentian University helps scientists understand how rivers moved on Mars.
"The data model he and Professor Mathieu Lapôtre of Stanford University developed could even be used to understand how rivers might have behaved on other planets such as Mars."
CBC News: Laurentian University professor's research could help prevent floods.
"A new article co-authored by Professor Alessandro Ielpi and published Dec. 2 in the journal Nature Geoscience could reshape the way we think about the interrelationship between plant life, rivers and the earth."
Sudbury.com: LU prof's paper on rivers could be used as basis for Mars research.
"This model, built from field work conducted in the Great Basin of the southwestern United States and from a compilation of satellite images depicting a number of rivers worldwide, contains many significant findings, not the least of which is the positive impacts of increased vegetation along river courses."
SciGlow: A tenfold slowdown in river meander migration driven by plant life.
"Broadly speaking, the more vegetation there is along a river’s edge, the longer it will take for the river to change shape. That has tremendous impacts on the environment, including the prolonged residence, and eventual capture, of organic carbon in floodplains."
Laurentian University News: LU Researcher publishes groundbreaking findings in Nature Geoscience.

"Today’s waterways could illuminate how ancient rivers helped to set the stage for life on land."
