Driven by the need for integrated management of groundwater (GW) and surface water
(SW), quantification of GW–SW interactions and associated contaminant transport has …

Geophysics provides a multidimensional suite of investigative methods that are transforming
our ability to see into the very fabric of the subsurface environment, and monitor the …

Fifty years of hyporheic zone research have shown the important role played by the
hyporheic zone as an interface between groundwater and surface waters. However, it is only …

Details of Earth's shallow subsurface—a key component of the critical zone (CZ)—are
largely obscured because making direct observations with sufficient density to capture …

Despite the wide application of hydraulic fracturing in enhanced geothermal system (EGS)
development and unconventional hydrocarbon production, our understanding of the many …

Interactions between groundwater (GW) and surface water (SW) have important implications
for water quantity, water quality, and ecological health. The subsurface region proximal to …

The conversion of bedrock to regolith marks the inception of critical zone processes, but the
factors that regulate it remain poorly understood. Although the thickness and degree of …

Groundwater and surface water, though thought to be different entities in the past, are
connected throughout the different landforms of the world. Despite being studied for quite …

Essentially all hydrogeological processes are strongly influenced by the subsurface spatial
heterogeneity and the temporal variation of environmental conditions, hydraulic properties …

Electrical geophysical methods, including electrical resistivity, time‐domain induced
polarization, and complex resistivity, have become commonly used to image the near …
