Experimental research for flushing the construction flood through the combination structures

Abstract

During the construction phase of large hydraulic and hydro-power structures, by flushing the construction flood through the culvert and the uncompleted spill way can help to reduce significantly the cost of diversion work as well as the total cost of construction. However, the hydraulic regime in this case is very complicated and used to be identified by a hydraulic model experiment. This article introduces the method to calculate and conduct the experiment of flushing the construction flood through the culvert and the uncompleted spill way for the SongBung 4 project.
