    Hi, I have seen from a large number of sources that river velocity increases downstream. However, I am quite confused on that.
    My teacher says it is inconclusive.
    Because gradient is steeper at the upper course, as well as snaller wetted perimeter.
    However, at the lower course, the hydraulic radius is larger as well as volume...
    tying to river velocity, is river energy higher in the upstream ir downstream course?

    There is more energy in a river downstream as there is more water so less energy is needed to overcome friction.
