     Because of the influence of tidal fluctuations,determination of aquifer parameters by using methods of pumping tests and recovery of groundwater levels becomes difficult and costs more in coastal areas.In this pa-per,through the study of the dynamic data of groundwater levels in the coastal aquifer in Beihai,Guangxi,we find that the rising and falling sections of the tide are asymmetrical.Based on the theory of the propagation of the sinusoidal tidal wave in confined aquifers,we provide a segmentation method to calculate the parameter of the aquifer,and compare the result with the those of the swing attenuation method and the time lag method.The ratios of storativity to transmissivity calculated with the three methods are close.This shows that the segmenta-tion method is effective.The S/T of the rising section is larger than that of the falling section in the coastal aqui-fer in Beihai.The mechanism needs further analyses.
