Discharge capacity of sluiceway channel of water intake structure for diversion power plant in winter

The paper presents results of research hydraulic processes at the intake structures of diversion power plants in winter. On the basis of the physical modeling results the flow characteristics of sluiceway channel of water intake on the river Issyk-Ata, Kyrgyzstan were determined. Statistical models of discharges of elements of sluiceway channel with their mutual influence were obtained, using the methods of experimental design and data analysis. The influence of the concentration of brash ice on the sluiceway channel and its elements is described. The comparison of experimental data with data obtained by other authors before is made by comparing flow coefficients. Recommendations for normal operation of ice pass at sluiceway track channel of water intake structure for diversion power plant are given.
