A new study led by the University of Colorado at Boulder indicates most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk.

Researchers at the University of Liverpool have discovered that the Amazon river, and its transcontinental drainage, is around 11 million years old and took its present shape about 2.4 million years ago.

Reductions in the flow of the Apalachicola River have far-reaching effects that could prove detrimental to grouper and other reef fish populations in the northeastern Gulf of Mexico, according to a new Florida State University study that may provide new ammunition for states engaged in a nearly two-decade water war.

Animals thrive on the banks of waterways. And those same tree-covered, green grassy areas are keys to maintaining healthy watersheds for creeks and rivers.

The Federal Opposition says the Commonwealth should be taking over management of the Murray-Darling Basin, not an independent authority.

Federal Water Minister Penny Wong expects a new statutory body set up to look after the Murray-Darling Basin will have formed a comprehensive plan for the river system by 2011.

Healthy streams with vibrant ecosystems play a critical role in removing excess nitrogen caused by human activities, according to a major new national study published this week in Nature.

Big rivers typically get the credit for being powerful and mighty, but a sweeping national study released today shows that when it comes to pollution control, even little streams can pack a punch.

If you have a good United States map handy, you'll see that the southern boundary of the mid-South state of Tennessee is a long, straight line along the 35th Parallel, which also forms the northern border of Georgia and two other states.

Arctic rivers transport huge quantities of dissolved organic carbon (DOC) to the Arctic Ocean. The prevailing paradigm regarding DOC in arctic rivers is that it is largely refractory, making it of little significance for the biogeochemistry of the Arctic Ocean.

In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part by studying one important segment - rivers.

Midwestern farming has introduced the equivalent of five Connecticut Rivers into the Mississippi River over the past 50 years and is adding more carbon dioxide annually into its waters, according to a study published in Nature by researchers at Yale and Louisiana State universities.
