NASA Satellite Data Find There Is Hope For Water In Aral Sea Basin
2014-02-14 14:25:27

Carol Rasmussen, NASA Earth Science News Team - NASA A new study using data from NASA satellite missions finds that, although the long-term water picture for the Aral Sea watershed in Central Asia remains bleak, short-term prospects are better than previously thought. Once the fourth largest inland sea in the world, the Aral Sea has lost 90 percent of its water volume over the last 50 years. Its watershed -- the enormous closed basin around the sea -- encompasses Uzbekistan and parts...

River Network, the leading conservation organization for the river and watershed community in the United States, commemorates its 25th anniversary this year, and just wrapped up a successful 14th annual River Rally in St Louis, Missouri. After Rally, longtime partner, board member and most recently President of River Network, Todd Ambs announced that he would be leaving River Network to return to his home watershed - The Great Lakes. Portland, Oregon (PRWEB) May 30, 2013 Network, the...

NASA To Map Snowpack Of Two Major Mountain Watersheds In Colorado And California
2013-05-03 09:00:35

Alan McStravick for redOrbit.com - Your Universe Online In the very near future, the global issue surrounding the need for natural resources will shift from fossil fuels to fresh water. In preparation for this change of need, NASA has endeavored on a new airborne mission to create the first maps of the entire snowpack of two major mountain watersheds in California and Colorado. These western snow reserves, as they melt, provide greater than 75 percent of the total freshwater supply for the...

Understanding how our water catchments react to natural disturbances, may offer hydrologists greater insight into how to manage our water supplies. Key to this, is an understanding of the steady state and why water responds differently in different circumstances. Dr Tim Peterson, from the School of Engineering at the University of Melbourne has offered new theories that will lead to a deeper knowledge of how water catchments behave during wet and dry years. His research was published...

American Water Resources Association (AWRA) Report Recommends U.S. Water Management Goals and Policies be Organized around Integrated Water Resources Management (IWRM) Middleburg, VA (PRWEB) January 20, 2013 The Policy Committee of the American Water Resources Association (AWRA) recently released its first national report examining the challenges and successes of integrated water resources management (IWRM) here in the United States. In 2011, the AWRA Board of Directors commissioned two...

Using Math To Better Understand River, Valley Networks
2012-12-06 16:23:13

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in a paper published in the Proceedings of the National Academy of Sciences (PNAS) that they have used math to explain different characteristics of river and valley networks. Rivers and valleys form intricate branching patterns, which have inspired some scientists to develop a theoretical understanding of river-network geometry. MIT scientists have created a mathematical theory to discover a common...

The University of Michigan and 20 other U.S. and Canadian universities will join forces to propose a set of long-term research and policy priorities to help protect and restore the Great Lakes and to train the next generation of scientists, attorneys, planners and policy specialists who will study them. The Great Lakes Futures Project of the Transborder Research University Network will use a cross-disciplinary, cross-sector approach to outlining alternative Great Lakes futures through...

Alan McStravick for redOrbit.com - Your Universe Online As a child, we all learned about how the rings of a tree could tell us how old the tree was. Did you know that now we can know how much rainfall occurred year-to-year through this same tried and true method? Well, with a twist. A research study led by a team from the University of Leeds has used tree rings from eight cedar trees in Bolivia to determine and document a 100-year history of rainfall across the Amazon River Basin, the...

Canada's Vast Mackenzie River Basin Has Major World Interests At Stake
2012-09-04 07:41:11

Watershed covers roughly 20 percent of Canada, including oil sands; The Mackenzie may discharge more water into the Arctic than the St. Lawrence into the Atlantic The governance of Canada's massive Mackenzie River Basin holds enormous national but also global importance due to the watershed's impact on the Arctic Ocean, international migratory birds and climate stability, say experts convening a special forum on the topic. "Relevant parties in western Canada have recognized the need for...

Climate Change Will Have An Effect On Basin Water Availability Nationwide
2012-05-21 03:13:33

Climate change projections indicate a steady increase in temperature progressing through the 21st century, generally resulting in snowpack reductions, changes to the timing of snowmelt, altered streamflows, and reductions in soil moisture, all of which could affect water management, agriculture, recreation, hazard mitigation, and ecosystems across the nation. Despite some widespread similarities in climate change trends, climate change will affect specific water basins in the U.S....

Endorheic Basin
2013-04-18 22:40:14

An endorheic basin, from the Ancient Greek endon, meaning “within” and rhein, meaning “to flow”, is a closed drainage basin that holds onto water and does not allow outflow to other external bodies of water, such as oceans or rivers, but joins instead into lakes or swamps, seasonal or permanent, that equilibrate via evaporation. Basins such as these might also be referred to as closed or terminal basin or as internal drainage systems. Usually, water that has built up in a drainage...

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....
