Reconstruction of subgrid scale topographic variability and its effect upon the spatial structure of three dimensional river flow (2010)
Journal Article
Casas, M., Lane, S., Hardy, R., Benito, G., & Whiting, P. (2010). Reconstruction of subgrid scale topographic variability and its effect upon the spatial structure of three dimensional river flow. Water Resources Research, 46(3), Article W03519. https://doi.org/10.1029/2009wr007756

A new approach to describing the associated topography at different scales in computational fluid dynamic applications to gravel bed rivers was developed. Surveyed topographic data were interpolated, using geostatistical methods, into different spati...

On the relationship between flow and suspended sediment transport over the crest of a sand dune, Río Paraná, Argentina (2010)
Journal Article
Shugar, D., Kostaschuk, R., Best, J., Parsons, D., Lane, S., Orfeo, O., & Hardy, R. (2010). On the relationship between flow and suspended sediment transport over the crest of a sand dune, Río Paraná, Argentina. Sedimentology, 57(1), 252-272. https://doi.org/10.1111/j.1365-3091.2009.01110.x

The links between large-scale turbulence and the suspension of sediment over alluvial bedforms have generated considerable interest in the last few decades, with past studies illustrating the origin of such turbulence and its influence on flow resist...

Coherent flow structures in a depth-limited flow over a gravel surface : the role of near-bed turbulance and influence of Reynolds number (2009)
Journal Article
Hardy, R., Best, J., Lane, S., & Carbonneau, P. (2009). Coherent flow structures in a depth-limited flow over a gravel surface : the role of near-bed turbulance and influence of Reynolds number. Journal of Geophysical Research, 114, Article F01003. https://doi.org/10.1029/2007jf000970

In gravel bed rivers, the microtopography of the bed exerts a significant effect on the generation of turbulent flow structures. Although field and laboratory measurements have indicated that flows over gravel beds contain coherent macroturbulent flo...
