Sediment Entrainment In Two Large Upland Gravel Bed Rivers (2023)
Thesis
Remers, A. (2023). Sediment Entrainment In Two Large Upland Gravel Bed Rivers. (Thesis). University of Salford

The sediment dynamics of river systems are of importance from an ecological, social and engineering viewpoint and are defined by complex relationships of various variables. Numerous threshold theories (such as Bagnolds stream power equation, Hjulstro... Read More about Sediment Entrainment In Two Large Upland Gravel Bed Rivers.

Impacts of river engineering on river channel behaviour : implications for managing downstream flood risk (2020)
Journal Article
flood risk. Water, 12(5), https://doi.org/10.3390/w12051355

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 sediment tra...

Evidence of non-contiguous flood driven coarse sediment transfer and implications for sediment management (2019)
Presentation / Conference
Heritage, G., Entwistle, N., & Milan, D. (2019, September). Evidence of non-contiguous flood driven coarse sediment transfer and implications for sediment management. Presented at 38th IAHR World Congress, Panama City, Panama

We investigate gravel redistribution and morphological response of three headwater streams following the Storm Desmond floods of December 2015. Reactive management of the watercourses following the flooding concentrated on removal of gravel and cle...

Drone based quantification of channel response to an extreme flood for a piedmont stream (2019)
Journal Article
Heritage, G., & Entwistle, N. (2019). Drone based quantification of channel response to an extreme flood for a piedmont stream. Remote Sensing, 11(17), 2031. https://doi.org/10.3390/rs11172031

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 moderated by...

Ecohydraulic modelling of anabranching rivers (2019)
Journal Article
Entwistle, N., Heritage, G., & Milan, D. (2019). Ecohydraulic modelling of anabranching rivers. River Research and Applications, 35(4), 353-364. https://doi.org/10.1002/rra.3413

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 single-thread...

Small unmanned aerial model accuracy for photogrammetrical fluvial bathymetric survey (2019)
Journal Article
Entwistle, N., & Heritage, G. (2019). Small unmanned aerial model accuracy for photogrammetrical fluvial bathymetric survey. Journal of Applied Remote Sensing, 13(1), 014523. https://doi.org/10.1117/1.JRS.13.014523

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 capture cross... Read More about Small unmanned aerial model accuracy for photogrammetrical fluvial bathymetric survey.

Multi-Scale detection, mapping, and modelling geomorphic change in gravel-bed rivers with UAV remote sensing (2019)
Thesis
Scott, R. Multi-Scale detection, mapping, and modelling geomorphic change in gravel-bed rivers with UAV remote sensing. (Thesis). University of Salford

Fluvial science is in particular need of surveying tools which can rapidly and accurately capture topographic data. The use of low-cost, consumer grade UAV (unmanned aerial vehicle) systems and Structure from Motion (SfM) processing methods has seen...

Meltwater temperature in streams draining Alpine glaciers (2018)
Journal Article
Williamson, R., Entwistle, N., & Collins, D. (2018). Meltwater temperature in streams draining Alpine glaciers. Science of the Total Environment, 658(Mar 19), 777-786. https://doi.org/10.1016/j.scitotenv.2018.12.215

Water temperature is of considerable importance with respect to lotic habitats. Water temperature influences physical, chemical and biological conditions within river environments and is, therefore, a key determiner of the health of a river. Climate...

Recent changes to floodplain character and functionality in England (2018)
Journal Article

Regime analysis suggests that temperate alluvial watercourses overtop their banks on average once every 1.5 years transferring water and sediment across the valley floor to form floodplains helping maintain a strong hydrological connection between in...
