The sustainable use of water resources requires clear guidelines for the management of
diffuse pollution inputs to rivers. Without informed guidelines, management decisions are …

The interface between groundwater and surface water within riverine/riparian ecosystems—
the hyporheic zone (HZ)—is experiencing a rapid growth of research interest from a range of …

The interplay between erosion and deposition are fundamental characteristics of river
basins. These processes result in the delivery, retention and conveyance of sediment …

Global quantitative estimations of ecosystem functions are vital. Among those, ecosystem
respiration and photosynthesis contribute to carbon cycling and energy flow to food webs …

Excess fine sediment, comprising particles< 2 mm in diameter, is a major cause of
ecological degradation in rivers. The erosion of fine sediment from terrestrial or aquatic …

Excessive sediment pressure on aquatic habitats is of global concern. A unique dataset,
comprising instantaneous measurements of deposited fine sediment in 230 agricultural …

Headwater streams are natural sources of methane but are suffering severe anthropogenic
disturbance, particularly land use change and climate warming. The widespread …

The significance of freshwaters as key players in the global budget of both carbon dioxide
and methane has recently been highlighted. In particular, rivers clearly do not act simply as …

Sediment plays a pivotal role in determining the physical, chemical and biological integrity of
aquatic ecosystems. A range of factors influences the impacts of sediment pressures on …

Ecosystem respiration is a primary component of the carbon cycle and understanding the
mechanisms that determine its temperature dependence will be important for predicting how …
