The application of rough strip energy dissipators is a new energy dissipation measure in engineering projects. In this study, the rough strips were installed to assist the energy dissipation in the curved channel of the “635” spillway remediation project in Xinjiang. By changing the layout of the rough strips, six different working conditions were set to analyze the water level change rate with the installment of rough strips, the surface line, the cross section uniformity, transverse slope of water surface, section velocity distribution, downstream water flow recovery length, section kinetic energy calculation and kinetic energy adjustment coefficient. The results showed that the installment of the rough strips could increase the water level change rate, and the change rate of the top section was different from that of the other sections of the bend in the curved channel. The increase of the height and the decrease of the interval spaces of the strips improved the flow regime in the bend and the downstream outlet. Through the calculation of the kinetic energy of the typical sections, we can see that the setting of the rough strips can greatly reduce the kinetic energy and change its adjustment coefficient. This indicates that the rough strip energy dissipators have a great adjustment effect on the flow energy, and performs well in assisting with energy dissipation of curved channels.
