In order to form the coastal landform from a beach to its inner shelf, a flume experiment was conducted using poorly sorted, very fine sand. The wave condition was stormy, and the wave base was above the bottom of the flume. In spite of the extreme settings, the shapes and grain size distributions of the resultant landform showed features similar to field examples reported in previous works. The sum of grain distributions of the sediments on the surface did not agree with that of the initial sand. This result indicates the importance of the underlying stratum in the estimation of grain size distribution of initial sand.
