Water discharging over weir with installed boom
This paper considers a possibility of booms application at spillway dams in order to reduce gates size and capacity of weight lifting device without changing weir discharge capacity. The prospects of booms application at weir top were proved during hydraulic researches conducted at JSC “NIIES” (Joint Stock Company “Scientific Research Institute of Energy Structures”). Basing on the conducted researches the recommendations of booms application at spillway facilities of Yumaguzinskaya and Upper Krasnogorskaya hydropower schemes, as well as at spillway facilities of Sayano-Shushenskaya and Plyavinskaya hydropower plants have been worked out. The main factor limiting wide application of booms at weirs is lack of feasible data for designing. At first, this data has to conclude methods of defining spillway discharge capacity and elevation of boom installation, which allows to keep the same spillway discharge capacity at rated head. The equations to define optimal elevation of boom installation and weir discharge capacity without its submergence have been analytically obtained for nappe-crested weir with installed boom. At the present time it is needed to conduct methodical experimental studies to define the discharge ratio and vertical compression according to different types of booms.
