Seagrass, kelp beds, mangroves, and other aquatic vegetation are often considered "ecosystem engineers" for their ability to essentially create their own habitats: Aquatic leaves and reeds slow the ...

The impoundment of the Three Gorges Dam on the Yangtze River begins in 2003 and a full pool level is first attained in 2010. This process leads to reciprocal adjustments in flow discharge, sediment ...

An international team of researchers has successfully captured the internal structure of the longest-runout sediment flow ever recorded on Earth. Using seismic measurements, the researchers have for ...

As a river cuts through a landscape, it can operate like a conveyer belt, moving truckloads of sediment over time. Knowing how quickly or slowly this sediment flows can help engineers plan for the ...

Soil erosion, which includes the processes of soil destruction, peeling, transport and deposition by external forces, is extremely complicated 1,2,3. Exploring the characteristics of runoff and soil ...

image: An MIT team has developed a more accurate formula to calculate how much sediment a fluid can push across a granular bed, which could help engineers manage river restoration and coastal erosion.

The flume is 15m long, 1m wide, and 50cm deep and is designed to study sediment dynamics. The flume has an adjustable slope (-0.5 to 2.0%) and will recirculate water and sediment at up to 0.2 cubic ...

Volatile rainstorms drive complex landscape changes in deserts, particularly in dryland channels, which are shaped by flash flooding. Paradoxically, such desert streams have surprisingly simple ...

A submarine landslide boulder preserved in 240-million-year-old deep-sea sediments, Dolomite Mountains. In November 1929, a large earthquake severed a transatlantic cable connecting Europe with the ...

Far below the surface of the sea, the seabed is being scoured by rivers of sediment that can flow thousands of miles from land. The river cascades through steep-sided gorges and churns around isolated ...
