Abstract: The accurate calculation of hydrogeological parameters is a prerequisite for the design of engineering schemes and numerical simulation of groundwater. In order to ensure the safety of construction, it is necessary to investigate the impact of Yangtze River tides on hydrogeological parameters. To illustrate, the Zhang Jinggao Yangtze River Bridge South Anchor Pit Project is employed as a case study. Utilising the observed Yangtze River tides, the daily high tide and low tide data from Tiansheng Tide Station, and the observed aquifer water level data, the lagging effect of aquifer water level on the Yangtze River tides is investigated through the application of cross-wavelet transform and wavelet coherence methods, with the data from the pumping test subsequently corrected. The findings indicate that the water level of the phreatic aquifer and confined aquifer exhibits a lag of 4.5-6 and 12-13 hours, respectively, in relation to the Yangtze River tides. Additionally, the Yangtze River tides exert a relatively diminished influence on the pumping test of the phreatic aquifer. However, the hydrogeological parameter calculations for the confined aquifer's three phases exhibit discrepancies, with errors reaching 11.09%, 6.75%, and 9.39%, respectively. It is therefore evident that the influence of tides must be taken into account in the calculation of hydrogeological parameters for the adjacent tide-sensitive river section..
