Which outcome is accelerated by concentrated fluvial erosion altering oxbow loop geometry?

💡 Explanation

Avulsion cutoff formation accelerates because concentrated fluvial erosion promotes neck erosion via headward channel migration, shortening an oxbow loop; therefore, a cutoff occurs, rather than continual sedimentation which would stabilize the loop geometry.
