- Nature has its own mechanism to protect coastal area. Predicting the evolution of beach profile especially the sand beach slope is important, in terms of coastal protection and environmental sustainability. Sand beach stability depends on the rate of sediment transport both long shore and cross-shore. The dynamic of beach alignment and slope may be resulted from the fluctuation of long shore and cross shore sediment transport. The beach profile characteristics, especially the stability of sand slope profile under various wave conditions, is probably the most important issue relevant to sand beach design. Flow characteristic is an important parameter to understand the dynamic of the stable condition process. This paper is focus on the study of flow characteristic of the stable slope profile due to regular wave on Ru – Rd area. The flow velocity on stable slope was studied using both theoretical and experimental approaches. A two-dimensional physical model was set up in the wave flume with regular wave. The experiment included the preliminary activities such as literature study, analysis of some recent interrelated research, investigation of new information, design for the experiment models and media, equipment for data acquisition, experiment’s materials, plan for calibration procedure and simulations.The results indicated that the K coefficient of the URu/URd depend on the angle of slope and wave steepness. In general for the slope of n = 6, the similarity between URu and URd is 0.89 – 1.2, with K = 6 – 8. Other results showed that the stable slope depend on parameter function in K coefficient and URu/URd.
