摘要
通过调查北仑河口北侧护岸工程的现状,分析研究海岸环境演变与水动力学之间的关系,发现北仑河口主航道向北岸偏移主要与由于科氏力作用产生的横向环流、夏季西南季风产生的强烈沿岸风浪流、台风强烈作用产生的风暴潮增水等这些动力条件有关。河口特殊地形的作用,河口区泥沙来源对河口主航道偏移的作用较小,但是人为干扰对加速主航道北侧河岸冲刷作用却不可忽视。
By means of analysis and research about Beilunhe estuary＇s project of protective bank actuality investigation, we found that the main sea-route northward movement in Beilunhe are related to the horizontal circulation generated by the Coriolis force,strong winds and waves along the stream generated by the southwest monsoon in summer, storm surges of water generated by the role of strong typhoons and other driving force conditions. The special terrain of the estuary and the estuary＇s sediment sources are not important. However, human disturbance to speed up the main channel of the river bank erosion on the north side effects should not be ignored.
