Physical model study for mitigating local scour downstream of clear over-fall…

Local scouring action downstream of clear over-fall weirs associated with three-dimensional turbulent flow field is a common morphological problem in mobile channel bed. The objective of this study was to assess and quantify the impact of hydraulic structural measures (double lines water jets) on minimizing the scour-hole dimensions downstream of a Fayoum type weir. Ninety runs were conducted c…
