Floodplain storage of water, nutrients, and sediment is critical to sustaining river ecosystems but has been reduced by human activities.
Geomorphology: fluvial
Researchers Home in on the Age of the Yangtze River
Findings on the river’s age also have implications for past landscape change in Asia.
Stream Hydraulic Geometry 1.01
New research provides a theoretical explanation of channel cross section geometry dependence on flow rate that is commonly observed and described with power-laws.
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.
Records and Risks of Legacy Phosphorus in Streams
A new study quantifies persistent phosphorus in a drainage basin in Sweden and points out risks and oversights to factor in to future stream management.
Meteoric 10Be Reveals Lithological Control on Erosion Rates
New meteoric 10Be data quantify fast erosion of slates in the Zhuoshui River catchment in Taiwan and demonstrate the influence of lithology on landscape steepness.
From Blowing Wind to Running Water: Unifying Sediment Transport
Laboratory experiments and grain-scale computer simulations during the past decade have led to a more universal understanding of flow-driven sediment transport across flows in oil, water, and air.
How Fast Did an Ancient Martian Delta Form?
Terrestrial meander migration rates are used to estimate a formation timescale of decades for Jezero delta on Mars.
It’s Time to Revise Estimates of River Flood Hazards
Accurately assessing flood hazards requires a better understanding of the feedbacks between natural and human influences on the characteristics of rivers.
The Shape of Watersheds
Streams in flatter watersheds have carbon cycles more sensitive to temperature increases.
