A numerical investigation into the importance of bed permeability on determining flow structures over river dunes (2017)
Journal Article
Sinha, S., Hardy, R., Blois, G., Best, J., & Sambrook Smith, G. (2017). A numerical investigation into the importance of bed permeability on determining flow structures over river dunes. Water Resources Research, 53(4), 3067-3086. https://doi.org/10.1002/2016wr019662

Although permeable sediments dominate the majority of natural environments past work concerning bedform dynamics has considered the bed to be impermeable, and has generally neglected flow between the hyporheic zone and boundary layer. Herein, we pres... Read More about A numerical investigation into the importance of bed permeability on determining flow structures over river dunes.

Modeling complex flow structures and drag around a submerged plant of varied posture (2017)
Journal Article
Boothroyd, R., Hardy, R., Warburton, J., & Marjoribanks, T. (2017). Modeling complex flow structures and drag around a submerged plant of varied posture. Water Resources Research, 53(4), 2877-2901. https://doi.org/10.1002/2016wr020186

Although vegetation is present in many rivers, the bulk of past work concerned with modeling the influence of vegetation on flow has considered vegetation to be morphologically simple, and has generally neglected the complexity of natural plants. Her... Read More about Modeling complex flow structures and drag around a submerged plant of varied posture.

Bed load tracer mobility in a mixed bedrock/alluvial channel (2017)
Journal Article
Ferguson, R., Sharma, B., Hodge, R., Hardy, R., & Warburton, J. (2017). Bed load tracer mobility in a mixed bedrock/alluvial channel. Journal of Geophysical Research: Earth Surface, 122(4), 807-822. https://doi.org/10.1002/2016jf003946

The presence of bare or partially-covered rock in an otherwise alluvial river implies a downstream change in transport capacity relative to supply. Field investigations of this change and what causes it are lacking. We used two sets of magnet-tagged... Read More about Bed load tracer mobility in a mixed bedrock/alluvial channel.

Flow resistance and hydraulic geometry in contrasting reaches of a bedrock channel (2017)
Journal Article
Ferguson, R., Sharma, B., Hardy, R., Hodge, R., & Warburton, J. (2017). Flow resistance and hydraulic geometry in contrasting reaches of a bedrock channel. Water Resources Research, 53(3), 2278-2293. https://doi.org/10.1002/2016wr020233

Assumptions about flow resistance in bedrock channels have to be made for mechanistic modeling of river incision, paleoflood estimation, flood routing, and river engineering. Field data on bedrock flow resistance are very limited and calculations gen... Read More about Flow resistance and hydraulic geometry in contrasting reaches of a bedrock channel.
