Must be a defining trait – Characters with access to vast powers (such as magical spells, advanced technology and genetic engineering) who are theoretically capable of this superhuman feature or ability – but who have neither made regular use nor provided a notable example of this extraordinary or supernatural feat – are not listed here.
The Water Quality Act of 1965 required states to issue water quality standards for interstate waters, and authorized the newly created Federal Water Pollution Control Administration to set standards where states failed to do so. No mechanism for federal enforcement was established.
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
Flood control channels are large and empty basins where surface water can flow through but is not retained (except during flooding), or dry channels that run below the street levels of some larger cities, so that if a flash flood occurs the excess water can drain out along these channels into a river or other bodies of water. Flood channels are ...
A flow control structure is a device that alters the flow of water in a stream, drainage channel or pipe. As a group these are passive structures since they operate without intervention under different amounts of water flow and their impact changes based on the quantity of water available.
h is the height of the water column in metres. A = area = rectangle: length × height measured in m 2 where: length = the horizontal length of a rectangular floodgate measured in metres height = the height of a non-submerged flood gate from the bottom of the water column to the water surface measured in metres
It arises through the need for flood control and irrigation, which requires central coordination and a specialized bureaucracy. [1] Often associated with these terms and concepts is the notion of a water dynasty. This body is a political structure which is commonly characterized by a system of hierarchy and control often based on class or caste.
