We have seen that the greatest limitation of the resistivity sounding method is that it does not
take into account horizontal changes in the subsurface resistivity. A more accurate model of …

The vadose zone (often called the unsaturated zone) is commonly defined as the geologic
media spanning from the land surface to the groundwater table of the first unconfined aquifer …

The hyporheic corridor (HC) encompasses the river–groundwater continuum, where the
mixing of groundwater (GW) with river water (RW) in the HC can stimulate biogeochemical …

Subsurface groundwater‐surface water mixing zones (hyporheic zones) have enhanced
biogeochemical activity, but assembly processes governing subsurface microbiomes remain …

Measurement errors can play a pivotal role in geophysical inversion. Most inverse models
require users to prescribe or assume a statistical model of data errors before inversion …

Temperature logs are an important tool in the geothermal industry. Temperature
measurements from boreholes are used for exploration, system design, and monitoring. The …

Time-lapse electrical resistivity tomography (ERT) measurements provide
indirectobservations of hydrological processes in the Earth's shallow subsurface at high …

Water resources, including groundwater and prominent rivers worldwide, are under duress
because of excessive contaminant and nutrient loads. To help mitigate this problem, the …

Hydrologic exchange flows (HEFs) across the river‐aquifer interface have important
implications for biogeochemical processes and contaminant plume migration in the river …

The hydrological characterization of the vadose zone remains a major challenge
considering the spatiotemporal variability of its properties and the limitations associated with …
