Abstracts:

The theoretical analysis of the effects of the longshore currents under the propagation of edge waves in the linear shallow water approximation over a cylindrical shelf. Detailed calculations are made for the model of "shelfstep" with a constant flow in the longshore zone. Analyzed the solution of the problem, constructed dispersion diagrams and cross-shore structure of the edge waves for different wave modes. The influence of longshore currents on the characteristics of linear edge waves. Demonstrated Doppler frequency shift for different wave modes for different values of the Froude number. It is shown the flow with parameters close to the real ocean parameters has only a slight effect on the dispersion properties and cross-shore structure of the edge waves.
