At present,single-point tidal level data are often used in the calculation of riding tidal level in channel design,which is better for the design of nearshore engineering and short channel. However,it is difficult to meet the urgent needs of safety and economy for deep-water long channel by single-point tide riding. The application of multi-point tide riding can greatly improve the accuracy of tide riding water level in channel design. It can ensure navigation safety of the channel and also can give consideration to the engineering economy. The problem of multi-point tide riding is studied by combining with engineering examples. The results show that by establishing the tide regression equation between multi-point tide stations and using the data of inshore stations to calculate to each section of the channel,the single-point tide riding can be converted into multi-point tide riding to solve the problem of the scarcity of multi-point tide level data. When conditions permit,it is suggested to carry out multi-point tide level temporary observation,and adopt tide level expansion method to make up for the lack of short-term data length and accuracy;when conditions are insufficient,it is suggested to calculate the tide level by means of numerical simulation,and verify the model with the measured data.
