A meander cutoff is an important geomorphological feature in fluvial landscapes that refers to the formation of an oxbow lake. The process of meander cutoff is a natural occurrence that happens when the river stream erodes the outer banks of a bend, causing the river to cut off the meander. Meander cutoffs are also called channelized cutoff, river avulsion, and oxbow cutoff. These terms are often used interchangeably depending on the specific context. Regardless of the term used, meander cutoffs can occur suddenly or gradually over time, ultimately leading to the formation of an oxbow lake that is no longer connected to the main river channel. Understanding terminology related to meander cutoffs is crucial for researchers and geographers studying fluvial landscapes.
