| Abstract: | Serious atomization occurs as hydraulic structures discharging high water head and large discharge,producing environmental pollution to hydraulic engineering and pepple's daily life and working conditions.It is an important problem which should be considered.Theories of measuremental methods used in prototype observation are presented in this paper.Radioisotope is applied to measure the atomization concentration in typical area.Stereophotogrammetry is applied to measure the shape and area of atomization flow.And atomization rainfall strength is measured by raing ages.The results provide scientific basis for the safe management of practical hydrauli cengineering and first hand data for the study of discharge atomization mechanism. |

| Keywords: | high dam discharge atomization environmental pollution stereophoto grammetry radioisotope |
