Three dimensional structure of nearshore currents is obtained by detailed measurements of velocity by Fiber-LDV using a plane wave tank. Vertical distribution of cross-shore velocity is similar to sum of uniform flow and velocity distribution of two dimensional wave flume. Vertical distribution of longshore velocity is nearly uniform flow. Velocity measurements of the upper reaches of trough level of wave are important, because vertical distribution of velocity changes rapidly at the nearly trough level.
