Study Finds River Bends Differ Significantly from Volcanic and Ice Channels

New research suggests the distinct curvature of river channels could help identify their origins on Earth and other planets.

Scientists at the University of Texas at Austin analyzed thousands of river, volcanic, and ice channel bends on Earth and the Moon.
The study found that rivers create more extreme bends due to sediment deposition, unlike volcanic and ice channels, which are shaped primarily by thermal erosion.
Distinct channel shapes could be used as a diagnostic tool to determine the origins of sinuous formations on planets like Mars and Saturn's moon Titan.
The research highlights differences in downstream bend patterns, with thermally eroded channels having more downstream accentuated bends than rivers.
Researchers caution that while the findings show potential, more data and analysis are needed for widespread application of this method.
