Abstract: To select the optimized scheme of Dongjiang River to Dongguan City water supply project, research was conducted on the scheme of river and reservoir connection. In the research, the merits and demerits of 3 water intake sites called Liyuzhou, Shajiao and Aositang are analyzed. 3 connection schemes of circular closure, circular non-closure, dendritic structure for 9 reservoirs called Songmushan, Luhuakeng etc. were compared. The scheme of water intake at Shajiao and circular closure was proposed, which can meet reservoir’s impounding demand of pumping from the Dongjiang River, increase water supply guarantee?for the central area as well as coastal area of Dongguan City, and ease water supply and demand contradiction.

Key words: river and reservoir connection, water intake, connection type, guarantee ratio of water supply, Dongguan City
