| 摘 要： | 应用Ecomsed模式，对黄埔—内伶仃区域采用曲线网格技术，从动力机制上分析珠江口虎门小尺度动力结构，结果表明：虎门上、下游呈现双向、不对称射流体系；凫洲水道的西侧注入射流体，严重影响着虎门的动力、沉积系统；落潮时，高浓度的悬浮泥沙通过凫洲水道，绕过鸡抱沙向东南呈舌状注入伶仃洋。

| Abstract: | The small-scale structure of Humen esturary of the Pearl River was dynamically analyzed by using ecomsed model and curvilinear grid technology. The results show that there is bi-orientation asymmetry jet system in the upriver and downriver of the Humen estuary. During ebbing, high concentration suspended sands pass through the Fuzhou channel and injects a tongue-like plume into the Lingding ocean bypass Jibaosha. The effluent injected from the western part of the Fuzhou channel makes a notable impact on dynamic and depositional system of the Humen estuary. |
