Which fluvial consequence results when river meander erosion breaches its narrow neck?

💡 Explanation

When a river meander breaches its narrow neck, the river shortcuts its course because it is the path of least resistance, isolating the meander bend from the main channel to create a crescent shaped oxbow lake. Therefore oxbow lake formation develops, rather than stream gradient decrease, downstream deposition, or rapid floodplain expanse, which all require different processes.
