Cohesive sediment particles are ubiquitous in environmental flows. The cohesive properties of clay promote the formation of clay flocs and gels and relatively small suspended clay concentrations can enhance or suppress turbulence in a flow. Furthermo...

Inadequacy of fluvial energetics for describing gravity current autosuspension (2023)
Journal Article

Gravity currents, such as sediment-laden turbidity currents, are ubiquitous natural flows that are driven by a density difference. Turbidity currents have provided vital motivation to advance understanding of this class of flows because their enigmat...

On the role of transverse motion in pseudo-steady gravity currents (2023)
Journal Article
Marshall, C. R., Dorrell, R. M., Keevil, G. M., Peakall, J., & Tobias, S. M. (2023). On the role of transverse motion in pseudo-steady gravity currents. Experiments in Fluids, 64(3), Article 63. https://doi.org/10.1007/s00348-023-03599-7

Flow in the body of gravity currents is typically assumed to be statistically two-dimensional, and cross-stream flow is often neglected (Simpson 1997; Meiburg et al. 2015). Here, we assess the validity of such assumptions using Shake-the-Box particle... Read More about On the role of transverse motion in pseudo-steady gravity currents.
