Hi Chegg Team,
I need some help with few questions here.
Please note: only state the answer. Thank you.
Question 11
A natural, meandering, river channel is artificially modified into a more straight, smooth, canal-like channel. Which one of the following statements is CORRECT?
The natural channel had a lower stream gradient AND less channel bottom friction than the modified, smoothed, straight channel.
The natural channel had a higher stream gradient AND more channel bottom friction than the modified, smoothed, straight channel.
The natural channel had a lower stream gradient AND more channel bottom friction than the modified, smoothed, straight channel.
The natural channel had a higher stream gradient AND less channel bottom friction than the modified, smoothed, straight channel.
There is no difference between the normal meandering channel and the modified straight channel, in terms of stream gradient and bottom friction.

Explanation / Answer
Answer : C
Meandering channels form where there is a less stream gradient and less bed load transportation
