The time after which material of more adult nature (violence, swear words, sex) may be broadcast on television or radio, either one laid down or one contrived (e.g. when children are not watching...)
The line of division between two adjacent rivers or lakes with respect to the flow of water by natural channels into them; the natural boundary of a basin
an event marking a unique or important historical change of course or one on which important developments depend; "the agreement was a watershed in the history of both nations"
The entire region drained by a waterway or into a lake or reservoir More specifically, a watershed is an area of land above a given point on a stream that contributes water to the streamflow at that point
The region draining into a river, river system or body of water; the total land area, regardless of size, above a given point on a waterway that contributes runoff water to the flow at that point; all the land that serves as a drainage for a specific stream or river
The total land area, regardless of size, above a given point on a waterway that contributes runoff water to the flow at that point It is a major subdivision of a drainage basin The United States is generally divided into 18 major drainage areas and 160 principal river drainage basins containing about 12,700 smaller watersheds
If something such as an event is a watershed in the history or development of something, it is very important because it represents the beginning of a new stage in it. The election of Mary Robinson in 1990 was a watershed in Irish politics = turning point
A ridge of high land dividing two areas that are drained by different river systems Also called a waterparting Also, the region draining into a river, river system, or other body of water
An area of land that drains water, sediment and dissolved materials to a common receiving body or outlet The term is not restricted to surface water runoff and includes interactions with subsurface water Watersheds vary from the largest river basins to just acres or less in size In urban watershed management, a watershed is seen as all the land which contributes runoff to a particular water body; all the land that serves as a drainage for a specific stream or river Imagine a maple leaf The stalk of the leaf is the river The veins threading into the stalk are the tributaries flowing into the river The complete leaf represents a river drainage system, or watershed
A watershed consists of all the land and waterways that drain into the same body of water Smaller watersheds join with other watersheds to drain into larger watersheds; thousands of smaller watersheds drain into large rivers like the Mississippi or Colorado rivers Coweeta was an ideal place to site a hydrologic lab because the area contains many sub-watersheds, allowing scientists to carry on numerous research projects without fear of contamination from adjacent projects An excellent primer on watersheds, including a utility that allows you to find the watershed where you reside
The entire region drained by a waterway (or into a lake or reservoir) More specifically, a watershed is an area of land above a given point on a stream that contributes water to the stream flow at that point
the land area from which surface water and groundwater drains into a stream system; the area of land that generates total runoff (surface flow, interflow, and baseflow) for a particular stream system
The drainage area of a stream, river, or other body of water There are nine gauged watersheds in the HBEF, ranging in size from 11 to 76 hectares, and researchers have conducted experiments on many of them Because these watersheds are similar to each other, researchers can experiment with one entire watershed (for example, by cutting all the trees down in the "treatment" watershed), leave another one alone ( the "reference" watershed), and then compare them If, in following years, the treatment watershed is very different from the reference watershed, scientists will learn how cutting down trees affects entire forests This type of experiment is referred to as a "paired watershed" experiment More information about watersheds can be found on Page 8 of the Introduction Tour
The area drained by a single stream or river The Arkansas River watershed, for example, includes that area from which water eventually flows into the Arkansas River
Land within the area of a drainage divide, or area wherein direct surface runoff from precipitation gravitationally travels to the same body of water Note how each watershed surrounds a stream or river Watersheds end where two streams come together and another watershed is formed to represent the larger stream The collection of watersheds that flows into a larger river such as the Great Miami River is known as a basin
The watershed is a time before which television broadcasters have agreed not to show programmes unsuitable for children, for example programmes that contain scenes of sex or violence. The advert should only be shown after the 9pm watershed
