Incipient Motion for Gravel Particles in Cohesionless Sediment Mixtures
Abstract This paper deals with the incipient motion for gravel particles in cohesionless sediment mixtures having silt and sand. The mixtures comprised of gravel–silt and gravel–sand–silt were used in the present experimental study. The critical shear stress for gravel particles was noted to be lower in the presence of silt particles. A formulation has been developed for the determination of critical shear stress of gravel particles. The governing factor includes the mean size of gravel particles, arithmetic mean of mixture, and the probability of hidden–exposure factor. The regression analysis as well as goodness-of-fit test was conducted for the proposed relationship which was found to be in good agreement with the data of present study as well as for other authors. The proposed formulation for the critical shear stress converges to Brownlie’s (1981) equation in case of uniform sediment.
