Abstract:
Compared with the qualitative study of seawater intrusion, the quantitative study can give a more direct description of the submarine groundwater discharge and inflow in the seawater intrusion area. We set up a 3-km-long monitoring section in an intertidal zone located in the north of Changyi City of Weifang. According to the data of groundwater level, water temperature, and conductivity, we conducted a quantitative estimation of the submarine groundwater exchange capacity by mathematical methods. The results of the calculation were used to evaluate the trend of seawater intrusion in the study area, and to provide a scientific basis for future groundwater monitoring in the area. The results showed that the inflow in the intertidal zone was obviously larger than the outflow , so the seawater is showing a trend of landward intrusion.
