freshwater marsh vegetation

Steve Hinnefeld, Indiana University 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. The study, "Optimum vegetation height and density for inorganic sedimentation in deltaic marshes," was published online Aug. 24 by Nature Geoscience. The findings may help guide restoration of river deltas, such as those near the mouth of the Mississippi River,...

Is The Western Wall In Jerusalem Wearing Away?
2014-08-13 03:48:17

The Hebrew University of Jerusalem Discovery Of Extreme Erosion Process Could Guide New Preservation Techniques Visitors to the Western Wall in Jerusalem can see that some of its stones are extremely eroded. This is good news for people placing prayer notes in the wall's cracks and crevices, but presents a problem for engineers concerned about the structure’s stability. The Western Wall is a remnant of the ancient wall that surrounded the courtyard of the Jewish Temple in...

Buried Fossil Soils Found To Be Rich In Carbon
2014-05-26 03:40:43

By Terry Devitt, University of Wisconsin-Madison Soils that formed on the Earth’s surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle. The finding, reported today (May 25, 2014) in the journal Nature Geoscience, is significant as it suggests that deep soils can contain long-buried stocks of organic carbon which could, through erosion, agriculture,...

Geophysicist And Mathematicians Team Up To Describe How River Rocks Round
2014-02-13 13:58:08

University of Pennsylvania For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river. Does this grinding reduce the size of rocks significantly, or is it that smaller rocks are simply more easily transported downstream? A new study by the University of...

Soil erosion may reveal ancient water management in Mahendraparvata Soil erosion and vegetation change indicate approximately 400 years of intensive land use around the city of Mahendraparvata in the Phnom Kulen region beginning in the mid 9th century, with marked change in water management practices from the 12th century, according to results published January 8, 2014, in the open access journal PLOS ONE by Dan Penny from the University of Sydney and colleagues from other institutions....

Economical Solutions For Maintaining Critical Delta Environments
2013-12-10 08:47:46

Woods Hole Oceanographic Institution Millions of people across the world live or depend on deltas for their livelihoods. Formed at the lowest part of a river where its water flow slows and spreads into the sea, deltas are sediment-rich, biodiverse areas, a valuable source of seafood, fertile ground for agriculture, and host to ports important for transportation. At least half of the deltas around the world are so-called “wave dominated deltas” – open to the sea and under the...

Virginia Institute of Marine Science Left to themselves, coastal wetlands can resist rapid levels of sea-level rise. But humans could be sabotaging some of their best defenses, according to a Nature review paper published Thursday from the Virginia Institute of Marine Science and the Smithsonian Environmental Research Center. The threat of disappearing coastlines has alerted many to the dangers of climate change. Wetlands in particular—with their ability to buffer coastal cities from...

The high cliffs of Eastern Siberia – which mainly consist of permafrost – continue to erode at an ever quickening pace. This is the conclusion which scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research have reached after their evaluation of data and aerial photographs of the coastal regions for the last 40 years. According to the researchers, the reasons for this increasing erosion are rising summer temperatures in the Russian permafrost regions as...

Rising Sea Waters Threaten Hawaiian Shorelines
2013-08-31 08:19:16

April Flowers for redOrbit.com - Your Universe Online In Hawaii, sea-level rise (SLR) has been isolated as a principal cause of coastal erosion. After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on the islands of Oahu and Maui. A new study,...

Erosion
2013-04-01 12:48:39

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,...
