Abstract

Abstract

The effects of longshore currents,Stokes mass transport by waves,large scale eddies and the instability of longshore currents on the transport of pollutant in a surfzone are discussed based on the experimental results.The physical experiments were conducted on the two plane beaches with the slope 1:100 and 1:40.The movements of pollutant(ink for the experiment) being injected into the water through point sources are recorded by a CCD camera,the fluid particle velocities and wave surface elevations were measured simultaneously.The experiment shows that the transport of pollutant is driven by Stokes mass transport outside the surfzone and by the longshore currents inside the surfzone,it also is affected strongly by the large-scale eddies and the instability of longshore currents.
