SAND SUSPENSION EVENTS AND INTERMITTENCE OF TURBULENCS IN THE SURF ZONE

[摘要] The results of the joint field experiment Norderney-94 demonstrates the excellent coincide of fluctuations of suspended sand concentration and kinetic turbulent energy in the nearbottom region of the surf zone. Turbulent fluctuations were separated from the wave induced fluctuations as a part of the motions that are incoherent to the free surface elevation. The time and spatial scales of macroturbulent vortexes had been estimated and discussed.
