Advanced numerical model is required in order to accurately simulate the breaking phenomenon. However, it is not suitable for practical application. Simultaneous coupling method (SCM) was developed by combining the efficiency of SWE with k-ω model for better bed stress assessment. Moreover, SCM employs FORCE-MUSCL shock capturing scheme to handle breaking wave. In this study, SCM is verified by simulating a breaking wave run up case. SCM provides a good agreement with the observed wave breaking sequence from the experiment by Sumer et al. (2011). Bed stress comparison shows that SCM with its boundary layer approach has successfully assessed bed stress under breaking wave run up, showing a better agreement than the Manning method. Further verification was given by the estimated turbulent intensity from SCM which shows good comparison to the measured bed stress fluctuation.
