{"Image DocumentName": "Aim- to describe and explain the formation of a variety of river features with the aid of annotated diagrams", "Image ImageDescription": "Within sections of the river channel, the flow tends to wind from side to side through a pattern of deep pools and shallower riffles. Riffles are formed by bed load deposits. A meander forms when the river channel bends, most of the water is directed to the outside of the bend. This reduces friction and increases the speed of the river at this point. The river therefore has more energy to transport through suspension, which will lead to erosion of the outside bank by corrasion. The bank will be undercut, collapse and retreat to leave a small river cliff. Meanwhile, there is less water on the inside of the bend, there is an increase in friction and a decrease in velocity. As the river loses energy, it deposits some of its load to form a slip off slope.
