Theoretical foundations for measuring and determining the flow rate of water delivered from reservoirs and canals to users
An analysis of the structures of water conduits for reservoirs and irrigation canals is conducted. Existing methods for measuring and determining the flow rate during water release from such structures are analyzed, and ways to implement these methods based on modern information-measurement and telecommunication technologies are investigated. In accordance with the goals and priority directions of the National Water Strategy of the Republic of Azerbaijan, the theoretical foundations for creating operational flow rate control systems in reservoirs and irrigation canals are developed on the basis of modern measurement and information-communication technologies. A structural diagram and components of a remote flow rate control and management system for distributed water supply networks supplied by reservoirs are proposed. Hydraulic processes in the water conduit structures of reservoirs and canals are analyzed, including variants of liquid discharge from thin-walled orifices into the atmosphere and under the water level, as well as local resistances causing additional pressure losses in the reservoir outlet tunnels. For more accurate calculation of the flow rate, it is proposed to determine the total resistance coefficient of the system by identifying practical losses for each specific case.
