Floodplain storage of water, nutrients, and sediment is critical to sustaining river ecosystems but has been reduced by human activities.
Findings on the river’s age also have implications for past landscape change in Asia.
New research provides a theoretical explanation of channel cross section geometry dependence on flow rate that is commonly observed and described with power-laws.
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.
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.
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.
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.
Terrestrial meander migration rates are used to estimate a formation timescale of decades for Jezero delta on Mars.
Accurately assessing flood hazards requires a better understanding of the feedbacks between natural and human influences on the characteristics of rivers.
The human eye is quite good at identifying channel networks among the rich patterns exhibited by estuaries and braided rivers, but computers have a harder time doing so. Could they do better?
