WebbThe settling velocity of sludge-water interface is always a constant, which is called the zone settling velocity (ZSV)[9]. The magnitude of the ZSV WebbRivers and streams carry sediment in their flows. This sediment can be in a variety of locations within the flow, depending on the balance between the upwards velocity on the particle (drag and lift forces), and the settling velocity of the particle.
