Question

_____allows the water to flow slowly into the rivers​

Answer 1

Answer:

Generally a narrower, more circular river channel allows faster flow of water. Broader flat channels tend to slow a river down.

Answer 2

Answer:

Explanation:

River has strong currents when flowing down from its mountain source. By the time it reaches the plains it slows down due to absence of good gradients & increase in width; and it is placid when it approaches the sea. There could even be reverse flow with high tide when there could be silting that neutralises any slope. So absence of strong gradients slows the river down.
