Coastal defence structures such as detached breakwaters have been used alternatively to reduce the coastal erosion problems in the world. Behind their efficiency, detached breakwater causes complex changes to the coastal hydro-morphologies because of variation in the sediment type, climate condition and design of the structures. This study aims to evaluate the impact of parameter changes of a detached breakwater on coastal morphologic changes. Three model cases of detached breakwater with different lengths and positions have been set up. MIKE 21 Mud Transport model interrelated with MIKE 21 Hydrodynamic model was performed to simulate the deposition-erosion patterns in the locality of detached breakwater for different lengths and positions of the breakwater. The results show that the detached breakwater with available empty gap gives lowest negative impact to the cohesive coastal areas with considerable reduction of the erosion problems.
