Abstract: This paper presents an experimental study of turbulent jets discharged vertically through a single circular submerged pipe into a large of stagnant non stratified water of finite depth. The experiments were carried out in the laboratory facilit ies consisting of a closed system capable of maintaining steady state conditions. The maximum water surface elevation is obtained for numerous flows,as function of jet energy flux and discharge depth The similarity of water surface elevation distribution was found,and its formula was got. The distribution of velocity in cross section and the rate of change of centerline velocity were obtained by the micro ADV system.
