Experimental Study on The Fall Velocity of Cohesive Sediments by Using Rotating Circular Flume
Author(s):
Abstract:
Determination of the fall velocity of cohesive sediment particles is very complex because of the adhesion properties of cohesive sediments and flocculation phenomenon. Therefore the deposition of fine sediments was investigated using an annular flume and in this work the hydraulic parameters was measured using Acoustic Doppler Velocimeter (ADV). Based on the experimental results the fall velocity of cohesive sediment was determined for different shear stresses values and different concentrations based on some empirical equations. The obtained results showed that a good agreement was observed between the Krone's equation and Burban's relationship. The obtained result from Lou and Krishnappan's method was inversely comparison the aforementioned equation. Finally, the results showed that the fall velocity is depended on the flow shear stress as well as the sediment concentration.
