In order to understand the external and internal flow structures of broken waves on a sloping bottom, a special design of run-up gauge combined with LDV measuring system is used to detect the velocity fields of run-up and run-down in our experiments. According to the experimental results, it is found that the heights of run-up and run-down are mainly determined by incident wave steepness. The dimensionless heights of run-up, run-down and the related swash length for different wave breakers are also discussed respectively. In addition, the elaborate measurements of flow structures, turbulent intensity and Reynolds stress in swash zone are also analyzed in this paper.
