Laboratory Investigation of Cross-Shore Sandbar Beginning and Ending Depths

Abstract

In the coastal regions, cross shore sediment transport causes significant changes in coastal morphology. In the design of structures such as sea walls, spurs and breakwaters, it is of great importance to accurately determine the movement of sediment in the onshore-offshore direction in filling and erosion and preventing them. In this study, experimental studies on cross shore sediment transport have been carried out with an initial shore slope of 1/8, 1/10 and 1/15. In the experiments carried out with regular waves having different deep-water wave steepness. The geometric properties of sandbar starting and ending depths formed under storm conditions for sediment average grain diameters d50 = 0.25, 0.32, 0.45, 0.62 and 0.8 mm were investigated.
