This work presents a simple method based on the defect law (Nielsen,1992) to reproduce the velocity vertical profile within the wave bottom boundary layer. The model results agree fairly well with the ADVP measurements and show that the defect law reproduces typical features of the oscillatory boundary layer: the velocity magnitude first increases with distance from the bed, with an overshoot at approximately 3 cm above the bed. There is a phase shift in the velocity that is maximum at about 1cm above the bed. Processing of the bed shear stress as well as velocities estimates within the sheet flow layer is under progress.
