On structures and control methods of joint streams regulation by two water power developments in satisfying water consumers' demands

摘要

The paper describes basic characteristics and maintenance conditions of Umaguzin and Nugush water power developments which were built in the Republic of Bashkortostan, Russia, in different time periods. The importance of water reservoirs formed as a result of their construction is stressed. The research shows the peculiarities of work, gives technical characteristics of these storage control structures and defines their key role in regulation of streams. Interrelationship of operating stages in the work of storage control water power developments is also underlined. As an example, the authors present their determinations of intermediate inflow coefficient of water flow. The paper reviews water consumers' demands for joint regulation of water course by different water power developments and for level-based operation of their joint afterbay. Some recommendations for satisfying these demands are given and economic effectiveness of these recommendations is estimated.
