This study aims to investigate all parameters that effect occurrence of breaking waves, these parameters selected according to physical phenomenon behavior and Buckingham theory procedure for proposing an expression that used to predict breaking waves performance. The results, mathematical dimension analysis with non-dimensional groups, shows that the parameters that have a major effect on the free surface phase at the braking moment can be summarized as: the depth of water (d), the height of wave (H), the length of wave (L) and the slope of bed (m) when compared with the other parameters of fluid properties and wave characteristics.
