Scour Estimation Downstream of Submerged Weirs
Publication: Journal of Hydraulic Engineering
Volume 145, Issue 12
Abstract
New laboratory data of local scour at submerged weirs are presented. The dimensionless scour depth downstream of a submerged weir in a uniform sediment bed is expressed as a function of dimensionless weir height, flow intensity, sediment coarseness, and weir slope. The existing and newly presented data are combined to evaluate the dependencies of downstream clear-water scour depth on each of the relevant dimensionless parameters. For live-bed scour, the limitations of the existing predictors are summarized.
