Experimental research on hydraulic regime for construction flow of Dardrinh hydropower project

Abstract

     Determination of the discharge in the construction stage is one of the most important content. It is depend on many factors that are very difficult to identify by theory, so an experimental work will be conducted in laboratory to find out the values of velocity, discharge capacity and dimensions of diversion work. The accuracy of the flow scheme in construction will be useful to reduce the construction cost and guarantee construction schedule in time.

    In Viet Nam, there are many large hydropower projects have been built, such as Se San 3; Se San 4; Ban Ve; Tuyen Quang; Cua Dat etc. Most of them use experimental to identify the hydraulic regime.

   This paper presents the results of hydraulic regime in construction flow of Dardrinh project.
