Abstract of the report：
This talk will illustrate how acoustic waves can provide a reliable means to measure the surface roughness in shallow water flows. A turbulent, shallow water flow is typically characterized by its dynamically rough water surface that carrier information on the hydraulic processes within this system. It has been suggested that the spectral and statistical characteristics of this surface can be related to the scale and intensity of the flow turbulent structures which cause the water surface to appear rough. These characteristics are very important for our better understanding of the hydraulic energy losses and the mixing processes in turbulent flows. It will be shown that these characteristics can be obtained from accurate measurements of amplitude, phase and the intensity of the acoustic signal scattered by the dynamically rough water surface.
