Experimental Studies on Flood Release and Energy Dissipation for Geheyan Project

This paper provides the experimental results on flood release and energy dissipation for Geheyan Project. By means of model tests, the multiple outlet works, including 7 overflow spillways, 4 medium outlets and 2 bottom outlets, which are situated at different elevation and different location in plane are adopted. The flip buckets with unsymmetrical flaring gate pier for the overflow spillways and unsymmetrical narrow slit for the medium outlets and bottom outlets are used as the dissipators.Using this layout of flood release and energy dissipation, the model tests indicate that the requirement of flood-carrying capacity can be satisfied and the high dissipating rate is obtained. These study results are used in the design of the Geheyan Project.
