Experimental Investigation of the Effect of Consolidation Time on Erosion Rate of cohesive sediment

The erosion of the deposited cohesive sediments by flow is a complex phenomenon. In general, hydraulic transmission of fine-grained sediments include depositional processes, consolidation and erosion. Cohesive sediments caused by physical-chemical effects on particle surfaces due to their strong ionic surfaces tend to form masses of low density or flocs. Depending on the conditions of the flow and resistance of the sedimentary masses, the erosion of sediments can occur in three different forms of floc, superficial and massive states (Mehta, 1991; Winterwerp and van Kestern, 2004). This study focuses on the effect of consolidation time on erosion rate of the deposited cohesive sediment in an annular experiment flume.
