Abstract: In order to study the relationships between flow fluctuating pressure of WES overflow weir’s stilling basin board and flow noise,it adopt-ed experimental modal to measure and record fluctuating pressure of stilling basin board and flow noise under the different rates of flow and levels of tail water. The analysis results show that water fluctuating pressure and noise value are increased with the increase of flow values;there are certain relationships between flow fluctuating pressure of stilling basin board and flow noise. Fluctuating pressure value’s maximum section is the same as stilling pool’s maximum noise value section,but possesses different variation trend respectively. Consequently,the main reason which causes water noise value owes to flow turbulence (the interaction between current)and interaction between water and solid wall.
