The serious damage of coastal dikes occurred in the tsunami caused by the 2011 off the Pacific coast of Tohoku earthquake. It is important to reinforce these coastal structures with the concrete blocks and to give the function of tenacious structures. In case of coastal dikes, the stability of concrete blocks and the damage of coastal dikes are affected by the strength of foundation in spillway and the fluid forces acting on concrete blocks armoring on slope just near the crest of dikes in the side of land for the over flow in tsunami. The relationship between the velocity distributions on concrete blocs and pressure distributions on the mound of slope, and the fluid forces and overturning moment acting on a concrete block adjacent to the crest of dike in the side of land. The forces and moment are measured by using a load cell.
