Applied hydromechanics, Vol. 4 (76) ¹ 3, (2002) |
The method of calculation of longshore currents and sediment transport in a near-shore area for an arbitrary bottom configuration and the line of a beach is offered. The method is based on refraction model with applying of average-out of amplitudes of water waves intersecting sides of grid elements. The field of longshore velocities is calculated on the base of theoretical formula given by Lounguett-Higgins with radiation stress using various models for definition of horizontal mixing. The sediment transport is determined following the models of White-Ackers, Grant-Madsen and Bijker. The comparative analysis of the approaches offered is given. |
