Meander cutoff geology
Webchute, or Cutoff, in a river, shortcut across a meander ( q.v. ). loop that shortens and straightens the course of the stream. Chutes are formed by lateral erosion of the bank of … 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 … See more A river constantly evolves and as it does, meanders that were once a part of the river are abandoned in favor of a route that is more efficient for a river to take. As these old meanders are cutoff from the rest of the river, a … See more A chute cutoff channel can form during a flood resulting in an overbank flow where water goes over the banks of the river, creating See more On 7 March 1876 a cutoff formed suddenly across the neck of a meander, known as the "Devil's Elbow", in the Mississippi River See more When either of these meander cutoff processes takes place a bend of the river is left behind forming, in many instances, an oxbow lake.
