Scour below a High Vertical Drop
Publication: Journal of Hydraulic Engineering
Volume 133, Issue 5
Abstract
Experimental results on scour below a high vertical drop (drop height/critical depth ) in uniform sands and gravels are presented. The experimental results are used to describe the effects of important parameters, identified from the dimensional analysis, on equilibrium scour depth. The important observations are that the equilibrium scour depth increases with increase in densimetric Froude number, whereas the scour depth decreases with increase in sediment size and tailwater depth. The time scale of scour depth that follows an exponential law is determined. The nondimensional time scale decreases with increase in densimetric Froude number.
