Document Summary
The numerous islands between these channels are made of sand and gravel and lack vegetation. These channels tend to be wider and more shallow than the other types. Braided channels often developing area where there is abundant bed load from melting glaciers. Velocity is greatest on the outside of the curves thus causing erosion and the formation of a cutbank. Slower water on the inside of the curves causes deposition and the formation of a point bar. Over time, the meanders get wider and the river lengthens. The volume of water flowing past a point in a river over a specific period of time.
