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. In fact, installation of new tile systems continues every year, because it leads to increased crop yields. But a recent study shows that the most heavily tile-drained areas of North America are also the largest contributing source of nitrate to the Gulf of Mexico, leading to seasonal hypoxia. In the summer of 2010...

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. The USGS has developed a new method for tracking the progress toward reducing nitrogen and phosphorus delivery from the watershed to the Bay. "The public and public officials care deeply about progress towards clean water goals for the Chesapeake Bay and other impaired waters of the Nation," said Robert Hirsch, USGS Research Hydrologist...

More accurate precipitation data leads to improved water quality modeling in the Chesapeake Bay NASA scientists improved watershed pollution monitoring models by incorporating satellite and ground-based observations of precipitation. The NASA data replaces weather station observations, and will allow states to monitor non-point pollution and improve water quality. The research team, led by Joseph Nigro of Science Systems and Applications, Inc., incorporated two NASA products into a computer...

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. For this purpose, a team of researchers has surveyed experts and has determined which basins in Spain have the most water problems. Given the subjectivity and uncertainty surrounding the assessment of Spanish water basins, scientists from the Facultad de Ciencias Econ³micas y Empresariales (Business School) of the University...

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 "“ the Ter, Foix, Gaia, Bes³s, Llobregat, Francolí, Tordera, Muga, and Fluvia. "This was a slow job, with its fair share of difficulties", Miquel Canals, one of the authors of the study and...

HARRISBURG, Pa., May 29 /PRNewswire-USNewswire/ -- Pennsylvania, New York City and other states in the Delaware River Basin, have reached two agreements regarding the plan that safeguards the drinking water supply for 15 million people and supports the basin's diverse wildlife habitat, Environmental Protection Secretary John Hanger announced today. Hanger credited the Pennsylvania Fish and Boat Commission for recommending the changes to the Flexible Flow Management Program, which governs New...

Sediments released by many of the world's largest river deltas to the global oceans have been changed drastically in the last 50 years, largely as a result of human activity, says a Texas A&M University researcher who emphasizes that the historical information that can be gathered from sediment cores collected in and around these large deltaic regions is critical for a better understanding of environmental changes in the 21st century.Thomas Bianchi, a professor in the Department of...

Bill Deutsch, of Auburn University, has launched a new project that is aimed at reducing farm runoff that has become a driving force behind water pollution in the Gulf of Mexico. The $300,000 project, funded by the US Environmental Protection Agency, will combine the efforts of colleagues in Veracruz, Mexico as a part of a three-year project to monitor pollution levels of water flowing into the Gulf. As a result of the study, Deutsch and colleagues hope to determine new methods that will...

The U.S. Environmental Protection Agency and U.S. Department of Agriculture should jointly establish a Nutrient Control Implementation Initiative (NCII) to learn more about the effectiveness of actions meant to improve water quality throughout the Mississippi River basin and into the northern Gulf of Mexico, says a new report from the National Research Council. The report also advises how to move forward on the larger process of allocating nutrient loading caps -- which entails delegating...

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....
