Timothy F. Brick, chairman of the board of directors of the Metropolitan Water District of Southern California, issues the following statement regarding the passing today of Dorothy Green, an environmental maverick on water issues who was one of the founders of Heal the Bay: "Dorothy Green has been a brilliant visionary and leader in the realm of water policy in California for many decades. A personal friend and mentor of mine for 35 years, Dorothy always exemplified a deep passion for...

By The Associated Press DES MOINES (AP) - Environmental groups in nine states petitioned the federal government on Wednesday to set and enforce pollution standards in the Mississippi River basin and the Gulf of Mexico.The petition to the U.S. Environmental Protection Agency followed Monday's announcement that the dead zone in the Gulf of Mexico is the second-largest to date at 8,000 square miles.The dead zone is an area of water where oxygen levels are too low to support marine life. It's...

By O'Riordan, Timothy Agriculture is beginning to be counted in the sustainability stakes. Agricultural runoff poses one of the most significant threats to physical and chemical water quality in the United Kingdom, according to the U.K. Department for Environment, Food and Rural Affairs. And, as Juha Siikamaki makes clear in his article, "Climate Change and U.S. Agriculture: Examining the Connections" (page 36), the agricultural sector contributes a significant amount of greenhouse gas...

A U.S. governmental task force has released a plan that involves state and federal officials in reducing hypoxia in the northern Gulf of Mexico. The plan, which includes proposals for improving water quality in the Mississippi River basin water, was released Monday by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force. It builds on recommendations issued in 2001 by incorporating innovative approaches and the latest science, including findings from the Environmental...

Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.The mathematics behind the new method also can be used to model and predict a wide range of other questions, from the transmission of waterborne illnesses to vegetation patterns on land adjacent to rivers.The researchers, who...

The world's rivers, lakes, reservoirs and groundwater as well as snow fields and glaciers are the main sources of freshwater to support terrestrial life and human livelihoods. Continuous observations are crucial to manage these water resources for the benefit of mankind and the environment and also to provide crucial forecasting services to prevent water-related disasters such as floods and droughts. These tasks are routinely undertaken by the National Hydrological Services of countries....

Zambian water authorities are integrating information based on satellite imagery to alleviate water shortages. With inadequate information causing many water-related problems, an ESA project has generated a variety of environmental maps to provide local policy makers with the necessary tools for effective water resource management. As part of the IWAREMA (Integrated Water Resource management for Zambia) project, funded through ESA's Data User Element, data from ESA's multispectral MERIS...

By Zampella, Robert A Procopio, Nicholas A; Lathrop, Richard G; Dow, Charles L ABSTRACT: We describe relationships between pH, specific conductance, calcium, magnesium, chloride, sulfate, nitrogen, and phosphorus and land-use patterns in the Mullica River basin, a major New Jersey Pinelands watershed, and determine the thresholds at which significant changes in water quality occur. Nonpoint sources are the main contributors of pollutants to surface waters in the basin. Using multiple...

By Bulley, Henry N N Merchant, James W; Marx, David B; Holz, John C; Holz, Aris A ABSTRACT: The U.S. Environmental Protection Agency is charged with establishing standards and criteria for assessing lake water quality. It is, however, increasingly evident that a single set of national water quality standards that do not take into account regional hydrogeologic and ecological differences will not be viable as lakes clearly have different inherent capacities to meet such standards. We...

COLUMBUS , Ohio -- As the Amazon River floods every year, a sizeable portion of South America sinks several inches because of the extra weight "“ and then rises again as the waters recede, a study has found. This annual rise and fall of earth's crust is the largest ever detected, and it may one day help scientists tally the total amount of water on Earth. "What would you do if you knew how much water was on the planet?" asked Douglas Alsdorf, assistant professor of geological...

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....
