An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream.
Either a river or stream forms a sinuous channel as the outer side of its bends are eroded away and sediments accumulate on the inner side, which forms a meandering horseshoe-shaped bend. Eventually as the result of its meandering, the fluvial channel cuts through the narrow neck of the meander and forms a cutoff meander.
Horseshoe Bend is a horseshoe-shaped incised meander of the Colorado River located near the town of Page, Arizona, United States. [1] It is also referred to as the "east rim of the Grand Canyon." [ 2 ]
Historically, the Oxbow was connected directly to the Connecticut river as a large U-shaped bend. [1] In 1840, flood waters cut through the narrow section, separating the Oxbow from the main river and the current. In the early 1900s, the Oxbow was used extensively for logging operations, as a holding area for logs sent down river.
Bight – Shallowly concave bend or curve in a coastline, river, or other geographical feature. Blowhole – Hole at the top of a sea-cave which allows waves to force water or spray out of the hole. Channel – Narrow body of water. Cape – Large headland extending into a body of water, usually the sea.
In domestic applications, traps are typically U, S, Q, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as an S-bend. It was invented by Alexander Cumming in 1775 but became known as the U-bend following the introduction of the U-shaped trap by Thomas Crapper in 1880.
Meander cutoff. A meander cutoff is a natural form of a cutting or cut in a river occurs when a pronounced meander (hook) in a river is breached by a flow that connects the two closest parts of the hook to form a new channel, a full loop. The steeper drop in gradient (slope) causes the river flow gradually to abandon the meander which will silt ...
An oxbow is a U-shaped metal pole (or larger wooden frame) that fits the underside and the sides of the neck of an ox or bullock. A bow pin holds it in place. The term "oxbow" is widely used to refer to a U-shaped meander in a river, sometimes cut off from the modern course of the river that formed it, creating an oxbow lake .
