Abstract

Abstract:

The special geomorphological structure of coral reefs causes most of the incident waves to break at the reef edge, thus effectively reducing the intensity of waves on the reef apron and protecting the coastal area. However, the increasing human activities on the reefs, such as coral sand blowing and shore defense construction, not only threaten the fragile ecosystems of the reefs, but also significantly affect the complex wave evolution characteristics of the reefs. Nowadays, the construction of islands and reefs is facing the dual needs of promoting the ecological restoration of islands and reefs and improving the characteristics of wave protection and resistance of islands and reefs. Based on a physical model test, this paper systematically investigates the evolution of solitary wave hydrodynamic characteristics of island reefs with the existence of artificial ecological reef groups and analyzes the influence of wave height, water depth, reef body opening diameter and other factors. The experimental results show that the existence of artificial ecological reefs will have a significant impact on the propagation and evolution characteristics of island-type solitary waves. There is a complex interaction between the incident wave and the artificial reef, and the presence of the reef enhances the reflective strength of the incident wave. In addition, the complex vortex field inside the artificial reef body will consume more incident wave energy, resulting in a lower transmission coefficient of the incident wave on the reef pads, which better protects the coast.
