Abstract

The phenomenon of breaking of surface gravity waves on the sea in a coastal zone has much in common with a steady hydraulic jump. When surface waves break a vortex forms which rolls down along the leading slope of the wave, as in the case of the formation of a hydraulic jump. Up to the present time a number of theoretical flow models have been proposed for the region in which a wave front breaks. Many of these studies are discussed in [1, 2]. However, the questions of the origin and dynamics of the vortex and its effect on the flow remain open. With the object of studying these questions in greater detail, the results are given below of numerical and experimental simulation of a hydraulic jump. The results of numerical calculations of the shape of the free surface and the velocity profiles in the various sections agree fairly well with the experimental data.
