AS Geog: Factors affecting river flow and velocity

Types of flow-Flow is subject to two main forces: GRAVITY (causes downstream flow) and FRICTIONAL RESISTANCE (with the bed and bank, opposing flow downstream). The volume of water within a channel and the shape of the channel affects the amount of energy a river has to move water and sediment. The type of flow in a river will affect the types of landforms produced by that river.

Turblent Flow-Not steady but chaotic. Turbulance provides upward motion in flow that allows the lifting and support of particles. Conditions: complex channel…
