O článku:
Broad-crested side weirs have been the subject of numerous hydraulic studies; however, the flow field at the
weir crest and in front of the weir in the approach channel still has not been fully described. Also, the discharge coefficient
of broad–crested side weirs, whether slightly inclined towards the stream or lateral, still has yet to be clearly determined.
Experimental research was carried out to describe the flow characteristics at low Froude numbers in the approach
flow channel for various combinations of in- and overflow discharges. Three side weir types with different oblique angles
were studied. Their flow characteristics and discharge coefficients were analyzed and assessed based on the results
obtained from extensive measurements performed on a hydraulic model. The empirical relation between the angle of side
weir obliqueness, Froude numbers in the up- and downstream channels, and the coefficient of obliqueness was derived.
