Experimental results of turbulent flows in the sea surface near the coastline have been performed using both Lagrangian and Eulerian methods, field tests are presented using video recordings and velocity sensors. The spatial and temporal resolution is limited by the measuring instruments, which results in “filtering” out the very small scales. The experimental field-results obtained during the large-scale surf zone experiments carried out in the Ebro Delta, (Spain), under spilling/plunging breaking waves are compared with experiments performed at the Barcelona harbour. The field-measurements include several tests across the surf zone with high vertical resolution. The measured turbulent properties are compared with macroturbulence characteristics and length parameterisations. Diffusion is measured and related to the local velocity spectra so that a generalized Richardson law may be used.
