Effect of semi-circular baffle blocks on local scour downstream clear-overfall weirs

(in lingua inglese)

The experimental and statistical study of local scour downstream of a Fayoum type weir with a horizontal apron with and without baffle blocks led to the following conclusions. The main flow characteristic is the development of a hydraulic jump from the initial super-critical conditions. The jump induces large secondary flows and clockwise vortices.
