Inflation of ponded, particulate laden density currents (2018)
Journal Article
Dorrell, R. M., Patacci, M., & McCaffrey, W. D. (2018). Inflation of ponded, particulate laden density currents. Journal of Sedimentary Research, 88(11), 1276-1282. https://doi.org/10.2110/jsr.2018.65

Field-based, physical modeling and analytical research approaches currently suggest that topographically confined particle-laden density currents commonly inflate to produce suspension clouds that generate tabular and texturally homogeneous sedimenta...

Optimisation of flow resistance and turbulent mixing over bed forms (2018)
Journal Article
Arfaie, A., Burns, A., Dorrell, R., Ingham, D., Eggenhuisen, J., & McCaffrey, W. (2018). Optimisation of flow resistance and turbulent mixing over bed forms. Environmental modelling & software : with environment data news, 107, 141-147. https://doi.org/10.1016/j.envsoft.2018.06.002

Previous work on the interplay between turbulent mixing and flow resistance for flows over periodic rib roughness elements is extended to consider the flow over idealized shapes representative of naturally occurring sedimentary bed forms. The primary... Read More about Optimisation of flow resistance and turbulent mixing over bed forms.

Scaling analysis of multipulsed turbidity current evolution with application to turbidite interpretation (2018)
Journal Article
Ho, V. L., Dorrell, R. M., Keevil, G. M., Burns, A. D., & McCaffrey, W. D. (2018). Scaling analysis of multipulsed turbidity current evolution with application to turbidite interpretation. Journal of Geophysical Research: Oceans, 123(5), 3668-3684. https://doi.org/10.1029/2017jc013463

Deposits of submarine turbidity currents, turbidites, commonly exhibit upward‐fining grain size profiles reflecting deposition under waning flow conditions. However, more complex grading patterns such as multiple cycles of inverse‐to‐normal grading a...

Particle Size Distribution Controls the Threshold Between Net Sediment Erosion and Deposition in Suspended Load Dominated Flows (2018)
Journal Article
Dorrell, R. M., Amy, L. A., Peakall, J., & McCaffrey, W. D. (2018). Particle Size Distribution Controls the Threshold Between Net Sediment Erosion and Deposition in Suspended Load Dominated Flows. Geophysical research letters, 45(3), 1443-1452. https://doi.org/10.1002/2017gl076489

The central problem of describing most environmental and industrial flows is predicting when material is entrained into, or deposited from, suspension. The threshold between erosional and deposi...
