| 摘 要： | 南渡三角洲沿岸在盛行ＮＮＥ向波浪等动力条件的作用下，泥沙产生纵向运移，岸滩遭受侵蚀或堆积，岸滩演变剧烈。本文利用基于网格的波注折射绕射模型，分析南渡江三角洲海岸波浪动力过程、破波带波能与辐射应力分布及其引起的沿岸泥沙纵向运称。浴海岸动力学地貌的角度，通过三角洲沿岸波浪动力特征、泥沙运动的分析，探讨沙质岸滩的动态与地貌演变。

| Abstract: | The grid-based regional coastal process wave numerical model (RCPWAVE) is used for predicting wave attack and consequent sediment transport patterns along the coastline of the Nandujiang Delta. The beach and nearshore evolution is described from the view of coastal morphodynamics, based on the analysis of wave dynamics and longshore sediment transport. The result shows that the prevailing NNE wind wave and westward longshore transport are the main causes of beach and nearshore evolution along the Nandujiang Delta. |
