Groundwater is by far the largest unfrozen freshwater resource on the planet. It plays a
critical role as the bottom of the hydrologic cycle, redistributing water in the subsurface and …

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

Stream temperature is one of the most critical factors controlling aquatic ecosystem health.
Practitioners and researchers from a range of fields, including biology, ecology, hydrology …

Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic
zone is a ubiquitous, reactive interface between the main channel and its surrounding …

Non‐perennial rivers and streams are ubiquitous on our planet. Although several metrics
have been used to statistically group or compare streamflow characteristics, there is …

Microplastics are abundantly found in streambed sediments, including both small and low-
density particles of neutral and positive buoyancy. Although the flow of water into streambed …

In this chapter, the authors provide a comprehensive analysis and synthesis of the
interactions between important drivers and controls of hyporheic exchange and …

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

We describe the hierarchical interplay of hydrology, hyporheic ecology and transformation of
nutrients and pollutants in the hyporheic zone (HZ). The exchange of water between the …

In this synthesis, we assess present research and anticipate future development needs in
modeling water quality in watersheds. We first discuss areas of potential improvement in the …
