Researchers from the Polytechnic University of Catalonia (UPC) have developed a method for evaluating the vulnerability of coastal regions to the impact of storms. The method, which has been applied on the Catalan coastline, shows that one-third of the region's coasts have a high rate of vulnerability to flooding, while 20% are at risk of erosion. "Until now there was no tool for evaluating coastal storm vulnerability that could quantify the processes and the probabilities of these events...

To understand the long-term effects of a prolonged tropical storm in the Panama Canal watershed, Robert Stallard, staff scientist at the Smithsonian Tropical Research Institute and research hydrologist at the U.S. Geological Survey (USGS), and Armando Ubeda, the LightHawk Mesoamerica program manager, organized four flights over the watershed to create a digital map of landslide scars. Two feet of heavy rain inundated the Panama Canal watershed between Dec. 7 and 10, 2010. Landslides tore down...

In one of his songs Bob Dylan asks "How many years can a mountain exist before it is washed to the sea?", and thus poses an intriguing geological question for which an accurate answer is not easily provided. Mountain ranges are in a constant interplay between climatically controlled weathering processes on the one hand and the tectonic forces that cause folding and thrusting and thus thickening of the Earth's crust on the other hand. While erosion eventually erases any geological obstacles,...

A study coordinated by Universitat Autònoma Barcelona (UAB) on the origin and evolution of peculiar morphologies created by ancient subterranean springs in the central pre-Pyrenees of Catalonia (Spain) pose new questions for planetary geomorphology research. Similar to small volcanoes, these formations until now had only been described in Australia and closely resemble gigantic forms found on Mars. The study may shed new light on the origin of these formations and the...

Drier conditions projected to result from climate change in the Southwest will likely reduce perennial vegetation cover and result in increased dust storm activity in the future, according to a new study by scientists with the U.S. Geological Survey and the University of California, Los Angeles. The research team examined climate, vegetation and soil measurements collected over a 20-year period in Arches and Canyonlands National Parks in southeastern Utah. Long-term data indicated that...

An assessment of coastal change over the past 150 years has found 68 percent of beaches in the New England and Mid-Atlantic region are eroding, according to a U.S. Geological Survey report released today. Scientists studied more than 650 miles of the New England and Mid-Atlantic coasts and found the average rate of coastal change "“ taking into account beaches that are both eroding and prograding -- was negative 1.6 feet per year.  Of those beaches eroding, the most extreme case...

Much of the Mississippi River's sediment load doesn't come from field runoff, according to work by scientists at the U.S. Department of Agriculture (USDA). Instead, the scientists with USDA's Agricultural Research Service (ARS) have confirmed that stream bank collapse and failure can be chief contributors to high sediment levels in the silty streams and rivers that flow into the Mississippi. ARS is USDA's chief intramural scientific research agency. The U.S. Environmental Protection Agency...

Scientists at the National Snow and Ice Data Center (NSIDC) in Colorado estimate that if global warming continues even at a moderate pace, a third of the earth's permafrost will be gone by 2200. A study released Wednesday, based on UN Intergovernmental Panel on Climate Change (IPCC) scenarios, warns that global warming could cause up to 60 percent of the world's permafrost to thaw by 2200 releasing huge amounts of carbon into the atmosphere increasing the rate of climate change, AFP is...

Desert greening
2013-04-25 16:10:03

Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...

Theodore Roosevelt National Park

Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt  first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...

Badlands national Park is located in the southwest region of South Dakota. It holds 242,756 acres of land, with 64,144 acres comprising a protected wilderness area. The park was designated as a national monument in 1929 and established in 1939, but attained national park status in 1978. The Stronghold Unit area of the park is managed by the National Park Service and the Oglala Lakota tribe and holds many sights including those used for Ghost Dances in the 1890’s, a bomb and gunnery range...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....
