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.

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.

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....
