| 摘 要： | 根据椒江河口的水文测验资料，分析了整治工程对河口动力沉积作用的影响。整治工程后使大、小潮时的涨落潮流速度普遍增大，落潮流速大于涨潮流速；涨、落潮流时含沙量增大，落潮时的含沙量大于涨潮；在涨、落潮流作用下，椒江口南槽受冲刷，深槽发育，北槽淤浅，浅滩发展。

| Abstract: | Influences of the regulation work on dynamic sedimentation in Jiaojiang Estuary, Zhejiang province, are analyzed based on measured hydro data. Analyses show that the regulation work will increase the spring and neap rates, and the flood and ebb tidal sediment concentrations. The rate and sediment concentration of the ebb tide is larger than that of the flood tide. Accordingly, the south channel will be deepened due to scouring and the shoals in the north channel will be developed as a result of silting. |

| Keywords: | action of tide current velocity sediment concentration regulation work Jiaojiang Estuary |
