Abstract
Seawater Intrusion is that seawater or saltwater intrude into the continent along the aquifer . Under the effects of the natural and artificial factors, the hydrodynamic conditions of aquifer in the coastal area has been changed ,which break the equilibrium between the seawater and the freshwater, hence the salt-fresh interface moves on the continent. Laizhou Bay suffers the most serious seawater intrusion in China. Based on analysis of the geological and hydro-geological condition in the study area, a flow and mass transport model has been developed to study the seawater intrusion in the area. Using FEFLOW software based on the finite element theory, this article solves the mathematic model and calibrates the model by long-term observation data of hydraulic head. Using the calibrated model it forecasts the evolution tendency of seawater intrusion. The modeling results showed that after 30 years total invasion of seawater intrusion in the area of about 4124 km2, and the serious invasion area of 2678 km2.
