Abstract Numerical study of the breaking criterion of solitary waves propagating on slopes was carried out by means of boundary element method, the algorithm was based on the Lagrangian description and finite differencing to time. The shoaling and breaking processes of solitary waves on various kinds of slopes are studied. According to the criterion defined as the horizontal velocity of water particle on wave crest equals to the wave celerity, our suggestions of breaking indices for slopes 1:10 to 1:50 are laid out, with which an empirical formula for the breaking indices was presented. In this article, the deformation of the wave profiles as well as the distribution of fluid velocities at the breaking region fo
