By the hydraulic model test the application feasibility of the roller bucket with low - ridge was demonstrated . comparing the hydraulic calculation data and operation rusultes , the article made some summarise . the principle of mixed flow for energy dissipation design has been well vertified through the study results
2.
The projects on the downstream of river are increasing recently . the common features of these projects are low head , low frounde number , large discharge ect . the roller bucket with low - ridge is applicated on the project for energy dissipation in the condition of low fr current and low head
