Abstract: Offshore artificial islands are one way to develop and utilize coastal areas. Since the early 1990s, more than 30 artificial islands of various sizes and purposes have been constructed off the coast of China, with most of them located along the sandy shoreline. In most cases, sandy coasts are erosive. The construction of offshore artificial islands also plays a significant role in mitigating coastal erosion. However, the alteration of the wave field due to artificial islands will inevitably impact the erosion and deposition patterns of sandy coasts. Taking the offshore artificial island of Hongtang Bay, Sanya as an example, the paper analyzes the changes in shoreline erosion and deposition before and after the implementation of the artificial island and its dynamic mechanism.
