Abstract:
Based on observation data of the Huili Chuan-31 well water level and local rainfall since Jan. 2019, we analyzed the relationship between groundwater level change and rainfall in different periods using the mathematical physics model in consideration of the characteristics of hydrological geology environment. The results of chemical composition and H and O isotopes of groundwater sample indicate that the groundwater in Chuan-31well circulates in shallow depth originates from the meteoric water. The result of this study may be helpful for seismic monitoring in the future.
