The Fifth International Planetary Dunes Workshop: From the Bottom of the Oceans to the Outer Limits of the Solar System; St. George, Utah, 16–19 May 2017
Plants and fluctuating river flow work together to balance vertical sediment buildup with sediment delivery to the delta’s edge.
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.
Researchers built a glass-encased test environment that helps them assess streamflow without the confounding factors introduced by bed forms.
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.
New geological findings suggest that an ancient flood in a popular legend about the birth of China's civilization might have actually occurred, but some 150 years later than historians thought.
River researchers find a mathematical relationship that predicts the average shape of a riverbed over a defined distance, opening the door to new ideas about modeling braided rivers.
A first-of-its-kind model describes how pools at the base of waterfalls adjust their depth to keep up with sediment flow.
Scientists examine the role of variables like tides and suspended sediment concentration to improve methods of evaluating coastal wetlands and how they may respond to future sea level rise.
The current definitions of sediment transport capability don't match up with observations of actual geomorphic systems.
