Latest Sediment Stories
The simple topography of dryland channels presents an interesting paradox according to scientists from UCSB’s Earth Research Institute.
Research by Indiana University geologists suggests that an intermediate amount of vegetation -- not too little and not too much -- is most effective at stabilizing freshwater river deltas.
Flow Science, Inc. announces the availability of a new release of FLOW-3D, version 11.
While flood-control measures have kept the Mississippi River from disrupting commerce and transportation along the waterways of southern Louisiana, they have also reduced the amount of wetland-preserving sediment flowing into the river’s delta.
University of Calgary-led research is first of its kind, uncovering the origin of oilsands sediment
For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream.
Millions of people across the world live or depend on deltas for their livelihoods.
Left to themselves, coastal wetlands can resist rapid levels of sea-level rise. But humans could be sabotaging some of their best defenses
Sediment behind milldams in Pennsylvania preserved leaves deposited just before European contact that provide a glimpse of the ancient forests, according to a team of geoscientists, who note that neither the forests nor the streams were what they are today.
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...
Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...
