Changes in ecosystem structure, function and hydrological connectivity control water, soil and carbon losses in semi-arid grass to woody vegetation transitions

open access: yes, 2013
Connectivity has recently emerged as a key concept for understanding hydrological response to vegetation change in semi-arid environments, providing an explanatory link between abiotic and biotic, structure and function.

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

Hydrological and sediment connectivity in three grazed Mediterranean hillslopes. [PDF]

open access: yes, 2017
Masselink et al. (2016) addressed the concept of connectivity addresses the spatial and temporal variability in runoff, sediment transport and associated substances such as pollutants and how these move through the catchment.

Using Trail Cameras to Monitor Culvert Connectivity in Wadeable Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Anthropogenic barriers in aquatic habitats have led to fragmentation and decreased fish diversity worldwide. Road crossing barriers such as culverts are a significant source of fragmentation and can impede aquatic organism passage (AOP). Many large extent efforts to inventory road crossing barriers and prioritize restoration efforts do not ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Getting a grip on hydrological and sediment connectivity

open access: yes, 2017
Land degradation is a large problem worldwide, especially in agricultural areas. Between 1-6 billion ha of land worldwide is affected by land degradation. With an increasing world population, more food production is needed and, therefore, more land is converted into agricultural areas.

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

A satellite-based framework for quantifying lateral hydrological connectivity: Insights for the Hungarian Danube River

open access: yesJournal of Hydrology: Regional Studies
Study region: This study focuses on the Hungarian reach of the Danube River, covering a 273 km section and its 14 hydro-morphological segments. The region includes regulated river sections and large floodplain systems, particularly the Gemenc floodplain,
