Abstract
To address the operational requirements of the 400 000 DWT waterway in Zhanjiang Port and the forthcoming S-100 series specifications,this study employs a tidal model combined with the residual water level method to evaluate the calculation accuracy of the astronomical tidal level field and water level field in the fairway waters.Tide model over the Chinese seas was employed as basic model.The accuracy assessment indicated that semi-diurnal tidal constituents show poor performance,and should been improved.The mean squares error in substituting the astronomical tidal level field for water level measurements ranges from 20.6 cm to 23.0 cm.Taking the Zhanjiang Port Station and Donghai Island Station,under the jurisdiction of the Guangzhou Hydrographic Center,as residual water level monitoring stations,the transmission accuracy of residual water level in the offshore vicinity from Zhanjiang Port to Donghai Island can reach 5 cm,and the accuracy of the water level field can reach 6.2 cm to 8.4 cm.The evaluation results provide guidance for improving the infrastructure supporting dynamic water level management in the fairway waters of Zhanjiang Port's.关键词
