The water…. There are three main types of processes that occur in a river. These are erosion, transportation and deposition. The characteristics of a river channel change along its long profile.

Changes occur in the cross profile, wetted…. Changing channel characteristics — cross profile, wetted perimeter, hydraulic radius etc Energy in a river Energy in a river is determined by three factors: mass of water; the height of the river above sea level; the gradient of the channel. Calculating the hydraulic radius of a river.
