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...

Topographic, hydraulic, and vegetative controls on bar and island development in mixed bedrock‐alluvial, multi‐channeled, dryland rivers (2020)
Journal Article
Milan, D., Tooth, S., & Heritage, G. (2020). Topographic, hydraulic, and vegetative controls on bar and island development in mixed bedrock‐alluvial, multi‐channeled, dryland rivers. Water Resources Research, 56(5), e2019WR026101. https://doi.org/10.1029/2019wr026101

We investigate processes of bedrock‐core bar and island development in a bedrock‐influenced anastomosed reach of the Sabie River, Kruger National Park (KNP), eastern South Africa. For sites subject to alluvial stripping during an extreme flood event...

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.

Recent changes to floodplain character and functionality in England (2018)
Journal Article
Entwistle, N., Heritage, G., Schofield, L., & Williamson, R. (2018). Recent changes to floodplain character and functionality in England. CATENA, 174(Mar 19), 490-498. https://doi.org/10.1016/j.catena.2018.11.018

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...

Quantifying and contextualising cyclone-driven, extreme flood magnitudes in bedrock-influenced dryland rivers (2018)
Journal Article
Heritage, G., Entwistle, N., Milan, D., & Tooth, S. (2018). Quantifying and contextualising cyclone-driven, extreme flood magnitudes in bedrock-influenced dryland rivers. Advances in water resources, 123(Jan 19), 145-159. https://doi.org/10.1016/j.advwatres.2018.11.006

In many drylands worldwide, rivers are subjected to episodic, extreme flood events and associated sediment stripping. These events may trigger transformations from mixed bedrock-alluvial channels characterised by high geomorphic and ecological divers...
