They do the most to even out the topography that tectonic processes create.
Rivers consist of a channel, bank and overbank or flood plain deposits.
Most of the sediment and many river characteristics are controlled by the highest common flow speeds. Braided Rivers - Braided rivers develop when the proportion bed load sediment is high, which produces abundant bedforms and promotes the development of bars, and thus, the braided character of the river. The sediment is commonly coarse, which requires fast flow and steep gradients. Erosion of bars up stream, deposition on downstream side of bars and some on the flanks of bars, particularly on the insides of bends. Secondary bedforms, i.e. planar beds, dunes, and ripples, form as a result of sediment transport on the bars and in the channels.
