The side of a levee in Sacramento, California. A levee (/ ˈ l ɛ v i / or / ˈ l ɛ v eɪ /), [a] [1] dike (American English), dyke (British English; see spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the banks of a river, often intended to protect against flooding of the area adjoining the river.
English: Diagram of a water distribution system. Inlet water goes through a pumping station. The water is delivered to the top of a water tank. Water pressure created by gravity and delivered to water mains. Water mains are connected to fire hydrants and service lines which are pipes that connect a water main to a building.
The slope of a levee is primarily a function of its grain size. [4] Levees tend to be steeper when they first form and are close to the channel, then gradually level out as they grow and their grain size decreases. [6] In the stratigraphic record, natural-levee deposits typically consist of thinly-layered sandstones overlying mud- to clay-sized ...
Instead, the water then enters the back swamps, or form a yazoo stream. [11] Because yazoo streams are separated from the main river by natural levees, they flow and meander (streams and rivers rarely flow in straight lines) parallel to the main stream channel or river on the floodplain for a considerable distance.
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system.
