Currently, many of the methods used to predict the effect of vegetation on river flow suffer from one or both of the following problems: (1) a strong dependence on parameters that have a poor physical basis and which are only readily determined using...

High-resolution numerical modelling of flow-vegetation interactions (2014)
Journal Article

In this paper, we present and apply a new three-dimensional model for the prediction of canopy-flow and turbulence dynamics in open-channel flow. The approach uses a dynamic immersed boundary technique that is coupled in a sequentially staggered mann... Read More about High-resolution numerical modelling of flow-vegetation interactions.

Effect of bed permeability and hyporheic flow on turbulent flow over bed forms (2014)
Journal Article
Blois, G., Best, J., Sambrook Smith, G., & Hardy, R. (2014). Effect of bed permeability and hyporheic flow on turbulent flow over bed forms. Geophysical Research Letters, 41(18), 6435-6442. https://doi.org/10.1002/2014gl060906

This paper uses particle imaging velocimetry to provide the first measurements detailing the flow field over a porous bed in the presence of bed forms. The results demonstrate that flow downstream of coarse-grained bed forms on permeable beds is fund... Read More about Effect of bed permeability and hyporheic flow on turbulent flow over bed forms.

Hydrograph convolution is a product of tributary inputs from across the watershed. The time-space distribution of precipitation, the biophysical processes that control the conversion of precipitation to runoff and channel flow conveyance processes, a...

Scales and causes of heterogeneity in bars in a large multi-channel river: Río Paraná, Argentina (2014)
Journal Article

To date, published studies of alluvial bar architecture in large rivers have been restricted mostly to case studies of individual bars and single locations. Relatively little is known about how the depositional processes and sedimentary architecture...
