This picture of the Nowitna River in Alaska shows two oxbow lakes – a short one at the bottom of the picture and a longer, more curved one at the middle-right. The picture also shows that a third oxbow lake is probably in the making: the isthmus or bank in the centre of the most prominent meander is very narrow – much narrower than the width of the river; eventually, the two sections of ...
Meander scars, oxbow lakes and abandoned meanders in the broad flood plain of the Rio Negro, Argentina. 2010 astronaut photo from ISS. A meander scar, occasionally meander scarp, [1] is a geological feature formed by the remnants of a meandering water channel. They are characterized by "a crescentic cut in a bluff or valley wall, produced by ...
The oxbow lake, which is the most common type of fluvial lake, is a crescent-shaped lake that derives its name from its distinctive curved shape. [37] Oxbow lakes are also known as cutoff lakes. [1] Such lakes form regularly in undisturbed floodplains as a result of the normal process of fluvial meandering.
Pull-apart basin – Type of basin in geology; Quarry – A place from which a geological material has been excavated from the ground; Rift – Part of a volcano where a set of linear cracks form; Sea cave – Cave formed by the wave action of the sea and located along present or former coastlines
A slough can form when a meander gets cut off from the main river channel creating an oxbow lake that accumulates with fine overbank sediment and organic material such as peat. This creates a wetland or swamp environment. One end of the oxbow configuration then continues to receive flow from the main channel, creating a slough. [13]
It is the largest oxbow lake in North America, as well as the largest natural lake in Arkansas. [2] The name Chicot, French for "stumpy," refers to the many cypress stumps and trees along the lake banks. [3] The lake is approximately 0.75 miles (1.21 km) wide and 21–22 miles (34–35 km) long from end to end. [4]
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 .
Kanwar jheel, as it is locally called, is located 22 km north-west of Begusarai Town in Manjhaul. It is a residual oxbow lake, formed due to meandering of Burhi Gandak [6] river, a tributary of Ganga, in the geological past. [7] It covers 2,620 hectares of the Indo-Gangetic plains in the northern Bihar State.
