Abstract

An evaluation model of the critical condition on armor block stability for submerged breakwaters was proposed by the author before (2011). However, the effect of the force normal to the block was not included in the model. Moreover, the drag and inertia coefficients were set to 1.0 as tentative values. In this study, the proposed model is improved by the inclusion of the wave force in the normal direction and the use of the fluid force coefficients determined by a 3D numerical computation.
