The effect of wave action on the establishment of Zostera japonica, a brackish submerged macrophyte growing mainly in coastal areas, is discussed. The wave forces acting on Z. japonica were measured by using a small two components load cell installed under the bed of wave flume. The wave forces were too small to pull out Z. japonica shoot from bottom sediment. Sediment transport and bed form development under waves were also observed, and Z. japonica shoot was pulled out from the sand bed of flume when large ripples appeared on the sand bed in wave flume.
