Abstract

This paper describes the experimental study of nappe oscillation at weir. We present how to suppress low frequency sound from nappe oscillation. Its sound can be suppressed by setting equipment at the lower end of a falling water sheet. Experimental results show the characteristic of nappe oscillation and effectiveness of the equipment on low frequency sound.
