We congratulate Dr. Jun Mitsui of Fudo Tetra Corporation, who graduated from Nadaoka Lab in March 2015, for winning the third prize of the PIANC De Paepe-Willems Award for his paper. The award ceremony took place during the Annual General Assembly of the PIANC held in Portugal on May 19. The paper is about the stability of breakwater armor units against tsunami. A practical design method for armor units to cover a rubble mound at the rear side of a caisson breakwater against tsunami overflow was proposed based on hydraulic model experiments and numerical analysis. The title of his paper is:

"New design method of armor units covering rubble mound of composite breakwater against tsunami overflow"
