| 摘 要： | 在现场观测资料分析基础上,应用波-流联合输沙模型,对粤东后江岬间海湾近岸带净环流、泥沙输运作用加以模拟分析,结果表明,东北东向风是形成近岸西南向净环流的主要驱动力,波浪控制了海底泥沙再悬浮和底质推移输运的过程,从而形成海湾海底地形以东北部侵蚀为主、西南部以淤积为主的发展趋势.

| Abstract: | On the basis of the analysis for data collected in field measurements, the model of combined wave and tidal current was used to simulate the residual current movements and sediment transport in the Houjiang nearshore area of East Guangdong,China. The results show that the northeastly wind is the dominant forcing to southwestly residual circulation currents, while waves control the resuspension of sediments and bedload transport processes. And the nearshore topography evolution is characterizeed by the trends of erosion for the northern area and deposition for the southern area. |
