Abstract
This paper describes the results of a laboratory study of air entrainment below drops for a range of Drop numbers from 0.0007 to 0.0046. Characteristics of the plunging flow that occurs when the tailwaler depth yt is in the range of yt* . to h were studied where yt* . is the value of yt when a hydraulic jump is formed at the section where Ihe deflected stream below the drop becomes parallel to the bed and h is the height of the drop. Air entrainment below the drop was studied for the jump with yt = yt* as well as for the plunging flows and approximate expressions have been developed for their air entrainment rates. These results can contribute to the estimation of the reaeration of polluted streams below drops.
