A novel approach to assess the cumulative impacts of thawing permafrost on aquatic systems using both Indigenous knowledge and western scientific knowledge Open
Increased temperatures and precipitation are intensifying mass wasting caused by the thawing of ice-rich permafrost in the western Canadian Arctic. Specifically, disturbances known as retrogressive thaw slumps deliver large quantities of s…

Using 2D Sediment Modelling to Simulate Geomorphic Change for River Restoration Initiatives Open
<p>River restoration projects have long relied on the use of modelling in both 1D and 2D to simulate the changes to flow hydraulics and flood extent that alterations to a river and floodplain will have caused. These methods have grow…

An investigation into the threshold of sediment motion, in two non-uniform English gravel-bed rivers Open
<p><em>The sediment dynamics of river systems are of significant importance from an ecological, social and engineering viewpoint and are defined by complex relationships of numerous variables. It is widely accepted amongst auth…

Effective and sustainable river restoration: 4D monitoring of a large upland gravel-bed river  Open
<p>Naturally functioning gravel-bed rivers are dynamic, highly biodiverse, well connected to their floodplains. They provide valued services to mitigate downstream flood wave propagation and storage of supplied sediment. Human-altere…

Impacts of River Engineering on River Channel Behaviour: Implications for Managing Downstream Flood Risk Open
Although knowledge of sediment transport has improved over the last 25 years, our understanding of bedload transfer and sediment delivery is still based on a limited set of observations or on models that make assumptions on hydraulic and s…

Topographic, Hydraulic, and Vegetative Controls on Bar and Island Development in Mixed Bedrock‐Alluvial, Multichanneled, Dryland Rivers Open
We investigate processes of bedrock‐core bar and island development in a bedrock‐influenced anastomosed reach of the Sabie River, Kruger National Park, eastern South Africa. For sites subject to alluvial stripping during an extreme flood e…

Drone Based Quantification of Channel Response to an Extreme Flood for a Piedmont Stream Open
The influence of extreme floods on the form and functioning of upland systems has concentrated on the erosive impact of these flows. They are seen to be highly competent with coarse sediment transport rates limited by upstream supply and m…

Ecohydraulic modelling of anabranching rivers Open
In this paper we provide the first quantitative evidence of the spatial complexity of habitat diversity across the flow regime for locally anabranching channels and their potential increased biodiversity value in comparison to managed sing…

Small unmanned aerial model accuracy for photogrammetrical fluvial bathymetric survey Open
Fluvial systems offer a challenging and varied environment for topographic survey, displaying a rapidly varying morphology, vegetation assemblage and degree of submergence. Traditionally theodolite or GPS based systems have been used to ca…

Flood energy dissipation in anabranching channels Open
This study examines the character of developing anabranched channel networks on the River Wear, north England, using metre‐scale aerial LiDAR. DSM‐DTM interpretation reveals a well‐developed vegetation structure and a locally diverse terra…

Morphodynamics of bedrock-influenced dryland rivers during extreme floods: Insights from the Kruger National Park, South Africa Open
High-magnitude flood events are among the world’s most widespread and significant natural hazards and play a key role in shaping river channel-floodplain morphology and riparian ecology. Developing conceptual and quantitative models for th…

Morphodynamic simulation of sediment deposition patterns on a recently stripped bedrock anastomosed channel Open
Some mixed bedrock-alluvial dryland rivers are known to undergo cycles of alluvial building during low flow periods, punctuated by stripping events during rare high magnitude flows. We focus on the Olifants River, Kruger National Park, Sou…

Recent remote sensing applications for hydro and morphodynamic monitoring and modelling Open
It is not new to recognize that data from remote sensing platforms is transforming the way we characterize and analyse our environment. The ability to collect continuous data spanning spatial scales now allows geomorphological research in …

Floodplains: the forgotten and abused component of the fluvial system Open
River restoration is strongly focussed on in-channel initiatives driven by fisheries interests and a continued

Anastomosing reach control on hydraulics and sediment distribution on the Sabie River, South Africa Open
Rivers in the Kruger National Park, South Africa, have variable degrees of bedrock and alluvial influence. Pre-2000 aerial imagery for the Sabie River (catchment area 6320 km2) reveals downstream alternations from alluvial single thread or…

Long-term flood controls on semi-arid river form: evidence from the Sabie and Olifants rivers, eastern South Africa Open
Rivers in the Kruger National Park, eastern South Africa, are characterised by bedrock-influenced "macrochannels" containing variable alluvial thicknesses and riparian vegetation assemblages. Evidence from the Sabie and Olifants rivers sug…
