Groundwater geophysics is a crucial interdisciplinary field connecting hydrogeology and geophysics,playing a pivotal role in aquifer structure identification,hydrological parameter inversion,and dynamic process monitoring.This paper reviews its primary methods,application advancements,and development directions based on techniques such as resistivity,seismic,electromagnetic,ground-penetrating radar,and nuclear magnetic resonance.These technologies each possess typical scales and sensitivities,with multi-method joint monitoring and petrophysics modeling serving as the core for quantitative interpretation.Current research has expanded from single-method structural identification to dynamic monitoring and process quantification under joint constraints,emphasizing the establishment of petrophysics relationship between geophysical and aquifer parameters to deepen understanding of aquifer heterogeneity,fluid transport,and multi-field coupling mechanisms.High-resolution detection in complex surface environments,data consistency in time-lapse monitoring,and non-uniqueness remain major challenges.Overcoming these bottlenecks requires advancements in signal enhancement technologies,better petrophysics models,and multi-field joint inversion frameworks to achieve a leap from qualitative interpretation to quantitative characterization.Future efforts should prioritize the development of high-resolution detection equipment,quantitative petrophysics models,time-lapse monitoring technologies,joint inversion frameworks,and AI-integrated methods.
