Which outcome occurs when the hydraulic gradient decreases sharply along a river flowing into a lake?

💡 Explanation

Alluvial fan deposition occurs because sediment-transporting capacity diminishes significantly due to reduced stream gradient, hence the flow spreads and dumps its load. Therefore, deposition forms a fan shaped deposit, rather than channel incision, altered oxygen, or meander changes.
