Document Type: Journal Paper


Methods of predicting the equilibrium depth of scour in a long constriction are presented. Relationships developed for the prediction of the depth of scour have been obtained by applying dynamic and static equilibrium theories and by verifying the dimensional analysis with the help of experimental data. The importance of the standard deviation of the particle size distribution of the sediment forming the beds in equilibrium scour problems is emphasized. A numerical example is presented to illustrate the calculation procedure.
