Using a vertical array of four streamer-type traps, the on-offshore sand transport rates were measured in the swash zone on three beaches. At the same time, water velocity and water level were measured. The vertical distribution of sediment concentration was obtained from the measurements. Concentration of onshore sediment transport was uniform from bottom to the upper part. The corresponding distribution for the offshore transport rate indicated that the sand transport was concentrated in the bottom layer.
