Which outcome occurs when rapid aggradation overwhelms channel avulsion in an alluvial system?

💡 Explanation

A crevasse splay results here because rapid sedimentation via aggradation raises the channel bed, leading to overbank flow and crevasse formation by channel avulsion rather than downcutting or floodplain entrenchment. Therefore, alluvial fans form.
