Due to the environment and navigation conditions, underflow energy dissipation is advisable to be employed in the design of Xiangjiaba Hydroelectric Project. However, it is rare in China and yet in the world to use such an underflow energy dissipater for such a high water head and a large flow discharge. With a great number of laboratory tests and studies, the high- and low-sill alternative has been proposed, with which the hydraulic indices are to be controlled within the acceptable range and that can well solve the issue of flood discharging and energy dissipation in the Xiangjiaba Hydroelectric Project.
