INCIPIENT MOTION OF HYPOTHETICAL STREAM BEDS—PART 2: CRITICAL SHEAR APPROACH
Critical shear criterion is followed to summarize the hydrodynamic conditions leading to incipient motion of spheres, of different sizes and densities, over-riding on a bed of closely packed spheres. A relationship governing the incipient motion conditions, based on critical shear stress criterion is developed, correlating the various physical properties of water and over-riding spheres, relative sizes as well as the inter-particle geometry of over-riding spheres and bed spheres. The results are generalized by showing their validity with others data of over-riding spheres on sphere-beds as well as on sand roughened beds. Results have indicated that conventional Shields' curve is not applicable because of protrusion height of the over-riding spheres over and above or below the general bed level, and an equation for Shields' parameter valid for over-riding spheres is presented.
