Longshore Energy Currents for Arbitrary Topography of the Bottom at Regular Rough Sea
ABSTRAKT
The computational method of longshore currents in a littoral zone with arbitrary bottom configuration and the line of beach is offered. The method is based on the refraction model with application of amplitudes averaging for the waves intersecting the sides of the grid elements. This allows avoiding the problems associated with results interpretation in the zone of ray intersection and specifying more exactly the field of water waves heights in the considered area. The breaking line is determined according to the Miche criterion on the base of calculated field of heights of the transformed waves. The field of longshore currents is calculated using the theoretical formula given by Lounguett-Higgins and Liu & Dalrymple.
