More than 75 years after its introduction, the seepage meter remains the only device for
directly quantifying exchange across the sediment-water interface between groundwater …

1| BACKGROUND Heterogeneities in sediment and rock permeability induce preferential
groundwater flow from the scale of pore networks to large basins. In the unsaturated zone …

Predicting baseflow dynamics, protecting aquatic habitat, and managing legacy
contaminants requires explicit characterization and prediction of groundwater discharge …

If accumulation is sufficient such that gas rises through the saturated sediment, preferential
flowpaths are created when gas rises to the overlying surface water, creating high-IK i …

Karst water resources play an important role in drinking water supply but are highly
vulnerable to even slight changes in climate. Thus, solid and spatially dense geological …

Direct groundwater discharge delivers nutrients from land and lakebed sediments to the
Great Lakes, which impacts lake water quality. Broad spatial distributions of discharging …

Groundwater–surface water interaction has received increasing recognition as a key area of
research that will improve our understanding of the global water cycle. Rather than treating …

At Lake Nørresø, Denmark, a suite of geophysical, traditional hydrogeological and two
surface temperature methods were combined to investigate how phosphorus-rich …

The efficiency of seepage meters, long considered a fixed property associated with the
meter design, is not constant in highly permeable sediments. Instead, efficiency varies …

Fluid flow and solute transport in geologic environments are vital for natural systems, public
well-being, and infrastructure that rely on understanding subsurface hydrology. Fractures …
