A V-shaped valley forms through a geological process called erosional downcutting in which a strong and fast moving river or stream erodes or cuts a path through rock. A V-shaped valley may also be referred to as a river valley.
Changing River Profiles. Changing River Profile. Before looking at specific river landforms it is important to look at how the river channel itself changes downstream. We have already looked at how the river channel in the upper course is shallow and narrow with large bedload that disrupts the efficiency of flow.t is common that rapids form over different bands of geology that vary in resistence or where the river is transporting large resistent bedload. The velocity of the river is noticeably faster at rapids but not efficient in its flow. Due to the roughness of the channel, flow is turbulent and known as white water.
