The shape of steep river streams changes systematically with channel slope, but field data and theoretical analysis reveal that slope is not the sole factor in setting a channel’s form.Read More »Hydrology, Cryosphere & Earth Surface
A study questions whether the hydraulics of rivers that lack loose sediments along their bottoms can be accurately depicted by standard equations for flow over sediment.Read More »Hydrology, Cryosphere & Earth Surface
A "big data" analysis of nearly 1 million river junctions in the contiguous United States shows that branching angles in dendritic drainages vary systematically between humid and arid regions.Read More »Hydrology, Cryosphere & Earth Surface
Mountain rivers and streams actively reshape landscapes by eroding material from uplands and depositing it in lowlands. Scientists can now predict this transport in very steep streams.Read More »Hydrology, Cryosphere & Earth Surface
Using Puerto Rico's Luquillo Mountains as a case study, scientists use the region's geological history to study how knickpoints—areas where there's a sharp change in the river's slope—move over time.Read More »
