Abstract
According to the tide level data of 8 main tide level stations at the Pearl River Estuary from 2001 to 2015, the long-term sequence of annual maximum tide level changes were analyzed through the Mann-Kendall trend analysis method, and its influence on the design tide level was explored, with a view to provide certain scientific references for the department of water conservancy project and management to formulate regional flood control planning and management. The results show that the annual highest tide level at the mouth of the Pearl River Estuary went upward from 2001 to 2015. The significance level of Dongsikoumen was lower than that of Xisikoumen, and the annual highest tide level of the Koumen site was constantly refreshed, leading to the increase of the design tide level, which will affect the flow capacity of the nearby sluices.
