Latest Sedimentology Stories
The Dutch beach in Monster is currently inhabited by bulldozers that are piling sand taken from the bottom of the North Sea into dunes in a determined attempt to protect the Netherlands from flooding.
While most people head to Myrtle Beach for vacation, a group of scientists have been hitting the famous South Carolina beach for years to figure out how to keep the sand from washing away.
Diverting sediment-rich water from the Mississippi River below New Orleans could generate new land in the river's delta in the next century.
The windswept deserts of northern China might seem an odd destination for studying the heavy monsoon rains that routinely drench the more tropical regions of Southeast Asia.
In a feat of reverse-engineering, Christian Braudrick of University of California at Berkeley and three coauthors have successfully built and maintained a scale model of a living meandering gravel-bed river in the lab.
A U.S.-led international scientific team says it has determined that Earth's river deltas are sinking due to human activity, many having recent severe flooding. The researchers, led by University of Colorado-Boulder Professor James Syvitski, found 24 of the world's 33 major deltas are sinking, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk. The study concludes the sinking of deltas from Asia and India to the Americas...
A new study led by the University of Colorado at Boulder indicates most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk.
U.S. scientists have developed an alternate theory for the origin of linear dunes on the surface of Titan, Saturn's largest moon, similar to ones on Earth. Louisiana State University Professor Patrick Hesp and U.S.
The paper, "Multiple origins of linear dunes on Earth and Titan," examines a possible new mechanism for the development of very large linear dunes formed on the surface of Titan, Saturn's largest moon.
Scientists from the Alfred Wegener Institute have researched the geology of the seabed in the Labrador Sea on board of the research vessel Maria S. Merian.
A river delta is a landform that is created at the mouth of a river, where the river flows into an ocean, estuary, lake, sea, or reservoir. These deltas are built from the deposition of the sediment that is carried by the river as the flow exit’s the mouth of the river. Over a long period of time, this deposition constructs the distinctive geographic pattern of a river delta. The creation of a delta is made up of three core forms: the bottomset, topset, and foreset/frontset. Bottomset...
In geology, a conglomerate is a rock consisting of other stones that have been cemented together. Conglomerates are sedimentary rocks consisting of subangular clasts and are thus differentiated from breccias, which consist of angular clasts. Both conglomerates and breccias are characterized by clasts larger than sand (>2 mm). There are two varieties of conglomerate, defined by texture: paraconglomerates and orthoconglomerates. Paraconglomerates are one of two varieties of conglomerate...
