     · In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders. In a stream, the most easily eroded particles are small sand grains between mm and mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow.
