Document Type: Journal Paper


The results of experimental and theoretical investigations are presented for certain sediment characteristics found pertinent to the control of localized scour in alluvial channels. The relationship between fall velocity of the sediment particle, velocity at the beginning of sediment motion, tractive force, and bed shear velocity is developed in terms of the nominal particle diameter. An example on the practical use of the data is provided. All results are presented in the form of graphs.
