Hydrotechnical Construction, 1975
Characteristic diagrams of the distribution of longitudinal velocities in the local scour zone at partly submerged obstructions are shown, and an equation is presented of dynamic balance of the flow around an obstruction during the the period of stabilization.

Local Scour Downstream of an Apron
Journal of Hydraulic Engineering, 1985Measurements have been made of the rate of scour downstream of a rigid apron due to a jet of water issuing through a sluice opening. Experiments are carried out for various sand sizes, sluice openings, efflux velocities, and lengths of apron. Mean velocity profiles in rigid models simulating the shape of the scour hole are studied in detail.

Local scour downstream of an apron with a swept-out hydraulic jump is shown to develop very rapidly, that is in less than 1% of the time to reach the ultimate scour depth. The short-term scour although not as deep as the long-term scour, occurs much closer to the apron.

Dimensional analysis of the variables influencing local scour at skewed piers brings into issue the generality of skew factors apparently related only to skew angle, α, and pier aspect ratio, L/b, for a particular pier shape. This note discusses this issue and provides insights into flow-field and scour-geometry changes at skewed piers.
