Which outcome occurs when high sediment input overwhelms fluvial transport capacity on a low-gradient plain?

💡 Explanation

Dominance of the alluvial fan formation occurs because rates of sediment deposition from upper slopes exceed the dispersal capacity, leading to deposition at the base of the slope. Therefore fans form, rather than deltaic structures which needs open body.
