Which outcome arises when silt accumulation obstructs flow?

💡 Explanation

A reduction in water flow occurs because sediment accumulation increases flow resistance; this is the mechanism of hydraulic friction. Lower resistance allows for more water flow because channel cross-section shrinks rather than altering boundary composition or flow properties.
