This gives the river a lot of potential energy. The river is trying to cut down to its base level so mainly erodes in a downward direction. This helps to create the v-shaped river valleys in upland areas. THE MIDDLE COURSE- As the river flows downstream the gradient becomes less steep. ...read more.

  2. Does the river Alyn follow Bradshaw's model?

    So we might uphold the assumption that velocity and discharge didn't increase downstream because the other variables with which they have a relationship didn't increase downstream. Therefore the evidence suggests that the theory on which Bradshaw's model is based

    Backstone Beck - The upper course of the river. Backstone Beck begins at grid reference 126460 and ends at 127483. Although the path taken by Backstone Beck is not completely straight it is neither particularly winding. There are a few large bends around interlocking spurs but most of the other bends in the beck are insignificant.
