Latest Drainage basin Stories
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.
A new 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 world’s largest river system.
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
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.
Tile drainage in the Mississippi Basin is one of the great advances of the 19th and 20th centuries, allowing highly productive agriculture in what was once land too wet to farm.
Reducing the delivery of nutrients to the Chesapeake Bay is one of the most important components of restoration efforts to achieve a healthy Bay ecosystem.
More accurate precipitation data leads to improved water quality modeling in the Chesapeake Bay.
There is some discrepancy among the scientific community as to the situation of reservoirs in Spain, one of the countries with the greatest water stress in Europe.
Despite the great difficulties in quantifying all the environmental and human factors that affect sediment discharge by rivers into the sea, a group of Catalan scientists has compiled data to describe and evaluate the solid sediment discharge from nine river basins in Catalonia â€“ the Ter, Foix, Gaia, BesÃ³s, Llobregat, FrancolÃ, Tordera, Muga, and Fluvia.
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....
