Geophysics provides a multi-dimensional suite of investigative methods that are transforming our ability to see into the very fabric of the subsurface environment, and monitor the dynamics of its fluids and the biogeochemical reactions that occur within it. The need for greater quantitative characterization of the subsurface has stimulated a wealth of new investigations into petrophysical relationships that link hydrologically relevant properties to measurable geophysical parameters. The development of time-lapse approaches has provided a new suite of tools for hydrological investigation, and improvements in inversion techniques allow us to better quantify properties and states of the subsurface environment. Early hydrogeophysical studies often concentrated on relatively small ‘plot-scale’ experiments. More recently, however, the translation to larger-scale characterization has been the focus of a number of studies. We illustrate, through a number of case studies, how geophysical techniques can give greater insight into the fabric of the subsurface and processes that exist within it. We also discuss current challenges and future opportunities. Hydrogeophysics continue to develop driven by the increasing need to understand and quantify key processes controlling sustainable water resources and ecosystem services.
