Abstract—The management of coastal aquifer is a hot topic in investigated in 2008, the river bed has certain permeability
many areas of the world. Using FEFLOW, a three-dimensional and the interaction between the seawater and groundwater
finite-element groundwater flow and solute transport model, has important functions on the groundwater quality. The
the response of the groundwater system on the impact of tide- locals are pursuit for better life environment when having
influenced river system at the estuary area of the Sand River better economic conditions. The study about the control of
was simulated. The model was well calibrated. The results saltwater intrusion is requested.
showed that, there was a significant influence of tide on the
area of pollute plume. Both the dam and hydraulic control can
effectively reduce the degree of saltwater intrusion. It is
suggested that the interaction between tide-induced river and
the groundwater system in coastal areas should be carefully
noticed.
