Abstract: Seawater intrusion has become a global coastal environmental problem. Because sea level change is a long and slow process, seawater intrusion tends to be difficult to predict. For regular sea level change, discussion of the tidal fluctuations influencing groundwater made it possible to predict seawater intrusion. Panel data have two dimensions, time and space, which can better represent the data from different individuals and time. In this paper, the influence intensity distribution of tides on apparent resistivity was analyzed by the panel data analysis method using continuous measurement of formation apparent resistivity data, and the influence of sea level rise on formation resistivity was predicted.
