摘要: |
海滩养护是砂质海岸最重要的自然防护手段之一,也是我国海岸带保护修复工程最重要的建设内容之一。围绕强波浪动力、弱波浪动力、强潮等不同条件下的养护海滩动力适应性与滩肩、沙坝等地貌稳定性及其模拟预测三个主要方面,总结近年来我国海滩养护基础理论和关键技术研究中的一些新认识和新思考,并提出亟需深入研究的重点内容。 |

Abstract: |
Beach nourishment is one of the most important nature-based solutions for sandy coastal resilience, and one of the most important contents of China’s coastal protection and restoration projects. Recent research advances on fundamental theory and key techniques of beach nourishment in China are reviewed, including the dynamic adaptability of beach nourishment under high-energy, low-energy and macro-tidal environments, the morphological stability of beach nourishment with respect to beach berm and sand bar, and the numerical modelling of nourished beach evolution. Further research prospects are also suggested. |
