Abstract

Experiments were conducted to determine the vertical profile of the longshore currents over plane and barred beaches. The logarithmic law is applied to fit the data for the region below the wave trough and an adjusted logarithmic profile without the mass transport velocity is applied to the region above the wave trough. The results indicate that the logarithmic law fits the data well for both plane and barred beaches. The friction velocity and the relative roughness obtained by the data fitting are compared with relevant calculated results.
