When a flood crest passes downstream,stream level falls more rapidly than it rose.

Question

Quizplus · Accepted Answer

The rise in stream level during a flood is typically rapid due to the sudden influx of water, but the fall in stream level after the flood crest passes is usually more gradual. This is because the excess water takes time to recede or be absorbed into the ground, and downstream flow may still be receiving additional water from tributaries or runoff.
