Which outcome occurs when a cutoff develops within meandering river bend?

💡 Explanation

An oxbow lake results from channel avulsion. River avulsion occurs because continued erosion and deposition causes the river to bypass a meander loop via a cutoff; therefore an oxbow lake forms, rather than the unaltered river flow.
