Abstract: A mathematical model for salt/ brine water intrusion into leaky aquifer system has been developed to simulate the spatial and temporal evolution of hydraulic heads and ion concentrations of the groundwater near the
east- northern coast in Laizhou Bay, Shandong Province. One important issue in developing mathematical model is to accommodate the nonlinear connection of the hydraulic head with the density and the viscosity of groundwater,
intercrossed effect caused by apparent concentration difference, positive ion exchange between water and soil, leaky actions. Also, log Kriging interpolation and rapid searching arithmetic of characteristic back points is shown to be
computationally efficient. The mathematical model is numerically solved to describe the motion of interface between salt water and fresh water in the southern beach of Laizhou Bay, the simulated values of the hydraulic head and the
ion concentration of groundwater agree very well with the field data, model is also verified by the data that is different from the calibration situation, results show that developing mathematical model is available.
