Longshore currents of regular waves on different beaches

摘要

The experiment and numerical computations of longshore currents produced by regularwaves on the two beaches with the slopes of 1:100 and 1: 40 are made. The cross-shore distributions oflongshore current velocities and wave heights are given and the influences of wave heights, wave periodsand beach slopes on the longshore currents are discussed. The discussion is also made for the influencesof different eddy viscosity coefficients on the numerical results of longshore current velocities.
