Experimental research for double layer flip bucket structure applying in spillway in the middle river

Abstract

     Design of spillway locating in middle of river having flow connection between spill body and energy dissipator in kind of flip bucket is depending on various factor such as discharge, velocity, depth of downstream flow, topographic and geological condition at downstream of spillway etc. Structure of flip bucket will be selected that satisfying the rational economic and technical requirements. One kind of mentioned flip bucket is double layer. For this kind, parameters such as angle of ski-jet in vertical and plan layout in horizontal direction will affect to structure. The paper is to present the research results for determination of hydraulic parameters in order to layout the plan of suitable double layer (slotted) flip bucket applying in flood discharge spillway locating in middle of river.
