Which risk increases when excessive sedimentation loads fluvial depositional fans?

💡 Explanation

Increased sedimentation accelerates channel aggradation on the alluvial fan because of depositional overloading; this promotes frequent channel avulsion rather than stable channel patterns. Therefore, channel avulsion is amplified rather than other sedimentary or weathering processes.
