Geoscientist Aids Study of Climatic Change Impacts on River Erosion
Scientists have long debated the idea that global climate changes have forced river erosion rates to increase over the past five million years. New...
New understanding of Mekong River incision
An international team of earth scientists has linked the establishment of the Mekong River to a period of major intensification of the Asian monsoon...
Between the lines: Tree rings hold clues about a river’s past
Hydrologists are looking centuries into the past to better understand an increasingly uncertain water future.
By analyzing centuries-old growth rings from trees in the Intermountain...
How Rivers Resist Erosion
Pop the top off a can of mixed nuts and, chances are, Brazil nuts will be at the top. This phenomenon, of large particles...
Rivers on three worlds tell different tales
The environment on Titan, Saturn's largest moon, may seem surprisingly familiar: Clouds condense and rain down on the surface, feeding rivers that flow into...
Amazon River no younger than 9 million years
Researchers from the University of Amsterdam (UvA) and the University of Brasilia (Brazil) have determined the age of the formation of the Amazon River...
Study shows how river channels adjust to large sediment supplies
The seemingly simple question of what governs the shapes of river channels has been a longstanding challenge for geologists and civil engineers. A new...
Rock layers preserve record of ancient sea tides near Blythe, California
Five million years ago, the Colorado River met the Gulf of California near the present-day desert town of Blythe, California. The evidence, say University...
Mississippi River could leave farmland stranded
If the Mississippi River continues to go unchecked, the farmland on Dogtooth Bend peninsula may be only accessible by boat. According to a University...
Fossils under your feet
Have you ever spotted something unexpected while walking down the street? Last December, paleontologists literally stumbled upon a new discovery of a fossil sea...
Incredible View for Mississippi River and Gulf of Mexico
The Dead Zone
The Gulf of Mexico hypoxic zone is a seasonal phenomena occurring in the northern Gulf of Mexico, from the mouth of the...
Antarctica’s “Upside-Down Rivers”
“Upside-down rivers” of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at...
Sudden shifts in the course of a river on a delta...
Scientists studying deltas show how they may be able to predict where destructive changes in a river's course may occur.
A delta forms when a...
Chemical weathering controls erosion rates in rivers
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can...
World’s large river deltas continue to degrade from human activity
From the Yellow River in China to the Mississippi River in Louisiana, researchers are racing to better understand and mitigate the degradation of some...
Cracking the problem of river growth
A general mathematical theory that predicts how cracks spread through materials like glass and ice can also predict the direction in which rivers will...
Eruptions impact on world’s rivers
Major volcanic eruptions can have a significant effect on the flow of the world’s biggest rivers, research shows.
In the first study of its kind,...
Engineering a better future for the Mississippi Delta
River deltas, low-lying landforms that host critical and diverse ecosystems as well as high concentrations of human population, face an uncertain future. Even as...
Japurá River
The Japurá River or Caquetá River is a river about 2,820 kilometres (1,750 mi) long rising as the Caquetá River in the Andes in...
How rivers creep, flow to shape landscapes over time
Rivers drive the evolution of Earth's surface by eroding and depositing sediment. But for nearly a century, geologists have puzzled over why theoretical models,...
