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,...

Lee Rannals for redOrbit.com - Your Universe Online New details published in the journal Nature reveals reasons behind why some mountain ranges exceed their expected lifespan. Interactions between landslides and erosion has helped scientists understand the reasons behind the lifespan of some of the world's iconic mountains. Researchers say this study answers questions as to why there was fast erosion in active mountain ranges in the Himalayas and slow erosion in others like the Great...

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,...
