BACKGROUND Early civilizations developed around seasonal river floodplains, and the
natural rhythm of rivers remains critical to humans today. We use streams and rivers to meet …

Watersheds play a critical role in supplying water resources needed for human use and
ecosystem health. Understanding and predicting how, when, and where changes in the …

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

Small ponds—farm ponds, detention ponds, or impoundments below 0.01 km2—serve
important human needs throughout most large river basins. Yet the role of small ponds in …

River connectivity maintains the transport of nutrients, organic matter, and organisms,
serving as a crucial link in global and regional biogeochemical cycles. However …

Ephemeral streams flow only in direct response to precipitation and are ubiquitous
landscape features. However, little is known about their influence on downstream rivers …

The physical and biological attributes of riverine ecosystems interact in a complex manner
which can affect the hydrodynamic behaviour of the system. This can alter the mixing …

River corridors integrate the active channels, geomorphic floodplain and riparian areas, and
hyporheic zone while receiving inputs from the uplands and groundwater and exchanging …

Dams and sluices break down the river continuum, alter the river hydrological regime, and
intercept the migration processes of nutrients and pollutants. The regulation of dams and …

The relative capacity for watersheds to eliminate or export reactive constituents has
important implications on aquatic ecosystem ecology and biogeochemistry. Removal …
