Previously regarded as the passive drains of watersheds, over the past 50 years, rivers have
progressively been recognized as being actively connected with off‐channel environments …

River‐groundwater interactions are at the core of a wide range of major contemporary
challenges, including the provision of high‐quality drinking water in sufficient quantities, the …

Transport processes and pathways through many hydrodynamic systems vary over time,
often driven by variations in total water storage. This paper develops a very general …

Interest in groundwater (GW)-surface water (SW) interactions has grown steadily over the
last two decades. New regulations such as the EU Water Framework Directive (WFD) now …

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

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

Although surface water and groundwater are increasingly referred to as one resource, there
remain environmental and ecosystem needs to study the 10 m to 1 km reach scale as one …

Time‐lapse resistivity imaging is increasingly used to monitor hydrologic processes.
Compared to conventional hydrologic measurements, surface time‐lapse resistivity provides …

Groundwater‐surface water exchange within the hyporheic zone is widely recognized as a
key mechanism controlling the fate of nutrients within catchments. In gaining river systems …

Human impacts such as timber harvesting, channel engineering, beaver removal, and
urbanization alter the physical and chemical characteristics of streams. These …
