Research on Fluctuation Numerical of Groundwater Level Near The Coast

LI Yang,TANG Zhonghua,LUO Meifang(College of Environmental Studies,China University of Geosciences Wuhan,Hubei 430074)  
There is a closely hydraulic relationship between the seawater and the unconfined aquifer near the coast.The water table of the unconfined aquifer near the coast fluctuates following the tide movement,the aquifer also exchanges water with the sea.Therefore,the seawater and the underground water can be considered as an interactional one.The article establishes a two-dimensional horizontal simulation model that combines the unconfined aquifer and the seawater coupling value and analyzes fluctuation features of the ground water level near the coast.The result shows that the fluctuation of groundwater level exist the phase difference and the amplitude attenuation characters by the landward distance from the coast increasing.And the water table also increases faster while the distance increases.
