Which outcome increases due to decreasing stream competence in alluvial fans?

💡 Explanation

Decreasing stream competence reduces transport capacity, thereby causing increased sediment deposition; this is caused by sediment supply overwhelming stream prowess because coarser sediments drop out more rapidly, therefore favoring intense deposition, rather than incision.
