hi im doin geo work i wud like to ask where is the velocity of a river highest the upper middle or lower?

Answer 1

the velocity of a river is its speed....a river runs fastest at the upper course, this is when it usually is flowing down a montain from the source, the middle course of the river its velocity slows down because there are meanders which are bends and curves in the river and at the lower it flows into the seas so there isn't much velocity there. If you have any more questions u can mail me

Answer 2

Velocity of water in a river is highest at the highest (top) layer. This is because the friction of the river bed and the viscosity of water.
Bottom layer of the river, in fact, is nearly stationary.

Answer 3

Are you refering to the different stages of rivers? If so, then you're looking for the "youthful" stage of the river where elevation drops rapidly.

Or in a vertical cross-section sense, I would think that almost the entire river would flow the same speed, with water near the bottom being slower due to variations in bathymetry.

Answer 4

Generally the other answers are correct, but their are instances when they are wrong. If you were to model a river correctly you will find alsorts of strange things happening. Whats it for, the data you need may be available.

Answer 5

It varies by river.

Answer 6

Try looking in a book.

Answer 7

think its lower cos got the stongest load there
