Stream Velocity VS. Sediment Size A streams velocity is 100 cm/sec. List the sediments that will be carried by the stream. A streams velocity is 40 cm/sec. List the sediments that will be carried by the stream. State the relationship between stream velocity and particle size. Describe how the size and shape of most pebbles change when the pebbles are transported in a stream over a great distance.
