    INCIPIENT MOTION CHARACTERISTICS OF COHESIVE SEDIMENTS

    New search for: Ansari, S. A.
    New search for: Kothyari, U. C.
    New search for: Ranga Raju, K. G.

    Results of an experimental study on incipient motion characteristics of cohesive sediments are presented. Cohesive sediments used consisted of medium sand mixed with Illite clay in different proportions. Incipient motion condition of thus formed cohesive sediment bed was identified through visual observations. Antecedent moisture content, clay content, plasticity index and void ratio/dry density are found to be significant parameters affecting the incipient motion characteristics in these cohesive sediments. A functional relationship between shear stress for incipient motion and sediment characteristics has been proposed based on dimensional considerations which account for both the plastic as well as non-plastic sediments. An empirical relation is also proposed for computation of Critical Shear Stress (CST) with certain limitations related to the type of clay used for experimentation and other factors.
