[DOC][DOC] Flow Characteristics and Energy Dissipation over Stepped Round-Nosed Broad-Crested Weirs
The main purpose of traditional broad-crested weirs is to rise and control upstream (U/S)
water level. In this study a new performance was added to this weir, by making it as an
energy dissipater. In order to study the energy dissipation percent (E%). The downstream
(D/S) height of the weir (12 cms U/S height) was reduced four times as 9.8, 8, 6and3. 8 cms.
Thirty experiments were performed in a laboratory horizontal channel of 12 m length, 0.5 m
width and 0.45 m depth for a wide range of discharge.
