Eco-hydro-morphodynamics and ecosystem services of near-natural river corridors
Near-natural river corridors (NNRs) provide crucial habitat for a host of biota and support the survival of people and nature worldwide at multiple spatiotemporal scales. Furthermore, NNRs represent fundamental references for river conservation, management, and restration, offering the opportunity …

Monitoring and Managing River Corridors in the Midst of Growing Water Demand
Rivers and their surrounding riparian and subsurface ecosystems, known as river corridors, are important landscape features that provide a myriad of ecological and societal benefits. While the importance of riverine flooding has been widely acknowledged and extensively studied, very little research …

Form and function: quantifying geomorphic heterogeneity and drivers in dryland non-perennial river corridors
Non-perennial rivers, including intermittent rivers and ephemeral streams, comprise the majority of drainage networks globally. However, ephemeral streams remain understudied compared to perennial counterparts, and the majority of extant studies focus on in-channel dynamics. Floodplains along …

Developing a virtual approach to determine if ecosystem service provision differs between Scottish river corridors with and without nature designations
… service provision differs between Scottish river corridors with and without nature designations. To achieve the primary research aim, this thesis has a secondary aim of developing a methodology which can capture multiple riverine ecosystem services at the reach scale. Following an extensive …

Towards an understanding of the effect of commercial/industrial activity on the quality of the recreation experience within urban river corridors
… outdoor recreation activities within an urban river corridor. In addition, the study specifies the relationship between social, psychological and use characteristics of these participants, and the degree to which their enjoyable recreational use of the urban river corridor is impaired by …

Responding to climate change in the design of the urban river landscape
… in professional bodies' workshops; in the corridors of government departments; in school classrooms and among the general public. There is also extensive amount of literature on the same subjects. Many recognise the problems and try to look for solutions. Climate change has impacted …

Spatial and Temporal Transitions in the Composition and Transport of Carbon under Variable Flow
… organic matter (DOM) cycling throughout river corridors or in reservoirs, but few have explored DOM cycling in commonplace but understudied run-of-river (ROR) reservoir systems. Impoundments disrupt river flow patterns, as they increase hydraulic residence time and alter the flow of DOM …

Numerical Simulation of the Propagation of Fine-Grained Sediment Pulses in Alluvial Rivers
… of loose sediment that are suddenly deposited in river corridors due to the action of external factors or processes of natural or anthropogenic origin. Such factors and processes include landslides, debris flows from tributaries, volcanic eruptions, dam removal projects, and mining-related …

A case study: Brown-green infrastructure in a semi-arid
… connectivity, multi-functionality, and “green”. River corridors are natural ecosystems considered as “Green” Infrastructure, which provide an interconnected network of “green” open spaces in cities. In terms of connectivity, Windhoek, Namibia, has three major ecological corridors along the Klein …

In the Zone: the Effects of Soil Pipes and Dunes on Hyporheic and Riparian Zone Hydraulics and Biogeochemistry
Streams and rivers are a vital part of our ecosystem. They are imperiled by human ecological activities such as urbanization, industrialization, and agriculture which discharge excess nitrate and other pollutants into our waterways. Here, this dissertation seeks to understand the physical and …

Fluvial and climatic controls on tropical agriculture and adaptation strategies in data-scarce contexts
… factors affecting tropical farming practices: river-floodplain dynamics and climate change. Despite data-related constraints, the environment of tropical rural areas still provides a unique opportunity to study several near-natural processes, such as the morphodynamics of mostly free-flowing …
