Abstract :
A breaking index appeared in the Boussinesq-type numerical model (Lynett, 2006) is replaced and tested. The new breaking index, which includes the water depth effect and is not sensitive to the spatial grid length, was first proposed by the Smith and Kraus (1991) and further optimized by many experimental data in this study. The numerical tests show that the modified Lynett´s model with this new breaking index is more stable and efficient in the nearshore breaking point computations. Comparison with Dingemans (1994) experiment shows the validity of the modified Lynett´s model in the nearshore wave breaking simulation.
