Which risk increases when a cutoff process shortens a fluvial meander?

💡 Explanation

River avulsions become more likely because meander cutoffs ( oxbow formation) causes channel slope increases; therefore, stream power concentrates, leading to rapid erosion driving potential sudden changes in the main channel's course; rather than gradual shifts.
