摘要
Abstract
The flow velocity changes in the tidal section of the lower reaches of the Yangtze River are complex,and in-depth research on the flow velocity characteristics and variation patterns are of great value for comprehensive watershed management.Based on the measured water level and flow data of Nanjing Station from January 1,2023 to July 31,2024,the cross-sectional flow velocity was calculated,the flow velocity range of Nanjing Station was statistically analyzed,and its variation law was further explored.The research results show that within one half day tidal cycle,the maximum flow velocity occurs near the lowest tide level during the ebb tide period,and the minimum flow velocity occurs near the highest tide level during the flood tide period.The flow velocity is closely related to both tide level and tidal range factors,positively correlated with tide level and negatively correlated with tidal range.关键词
