DISCHARGE COEFFICIENT OF BROAD-CRESTED WEIRS AS A FUNCTION OF THE RELATIVE WEIR HEIGHT FOR DIFFERENT WEIR LENGTHS

Broad-crested weirs (BCW) are often used in hydraulic engineering and water management. The most complex factor that affects the discharge capacity of BCW is the discharge coefficient. In Ukrainian engineering practice, the flow rate of BCW is defined as a function of the relative height of the spillway wall, while in the most common European methods – as a function of the relative length of the weir.
