Abstract
Fluctuations of force exerted on the sill of a forced hydraulic jump have been measured and presented in terms of their root-mean-square values. Experiments involved a wide range of flow conditions, various distances of the sill from the efflux, and four different heights of the sill. Maximum intensity of force fluctuations occurs when the toe of the jump begins to be sensitive to the depth downstream of the sill. Under those conditions, the spectra of fluctuations exhibit a dominant frequency. At high submergence the intensity depends essentially on the height of the sill.
