Question

Along straight stretches of a stream channel, the highest velocities of water are found _____.

Answer 1

Answer:

Highest stream velocities exists at the mid channel near the surface of water

Explanation:

The highest velocity in a straight channel is found in the mid channel near the surface of water as there in no friction from the bed channel. On the other hand the velocity of a stream at the bank side and bed is the lowest as there is the highest friction caused by the roughness of the substrates constituting the  bank/bed.

Answer 2

near the water surface in the center of the stream
