| 英文摘要 | Understanding of saline intrusion into coastal aquifer is an important issue in management and protection of groundwater resource, which can be well achieved by groundwater modelling. To explain some phenomena of correlation between groundwater level and salinity in observation wells in coastal area, the authors compare the migration velocity of saline particles and transmission velocity of water pressure and derive analytical equations of these two velocities for plane and radial flows. The driving force and resistance of saline intrusion were analysed based on the analytical modelling. The destruction and reconstruction of the equilibrium between fresh water seepage towards sea and saline dispersion to inland were considered as an essence of whole intrusion process. The dynamic process of seepage and dispersion at different stages of saline intrusion were analysed under groundwater over-exploitation. The basic equations of saline intrusion were derived and the mechanism of transitional zone movement was discussed. These constitute coupled seepage-dispersion theory of saline intrusion, which becomes an important supplement to existing theory of saline intrusion. As a case study on saline intrusion in Guangrao County in Eastern China, this theory was applied to predict the development of saline intrusion in the study area. |
