This study develops a threedimensional heterogeneous densitydependent numerical model to simulate the seawater intrusion process in coastal aquifers in Zhoushuizi District,Dalian City.To identify the hydrogeological parameters of the aquifers in the study area,the model was calibrated and validated using the observed head and concentration data.According to the current groundwater abstraction conditions in this study area,the calibrated and validated model was applied to predict the dynamics and trend of seawater intrusion for the following 30 years from 2010 to 2040 with and without tidal effect.Prediction results showed that the overall extent of seawater intrusion in the future would be even more severe considering tidal effect.This threedimensional seawater intrusion model provides the theoretical basis for controlling the further deterioration of groundwater quality and the rational allocation of groundwater resources in coastal aquifers.
