Thesis
Pickett, B. (2025). Tsunami Risk to UK Offshore Wind: Paleo-evidence and numerical model simulation. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/5126372

The UK produces over 45% of its energy through renewable means, the majority of this through wind power. The mainstay of this capacity is located offshore in the North Sea, a region and capacity which is set to significantly expand in the coming year...

The transport and vertical distribution of microplastics in the Mekong River, SE Asia (2024)
Journal Article
Mendrik, F., Hackney, C. R., Cumming, V. M., Waller, C., Hak, D., Dorrell, R., Hung, N. N., & Parsons, D. R. (2025). The transport and vertical distribution of microplastics in the Mekong River, SE Asia. Journal of hazardous materials, 484, Article 136762. https://doi.org/10.1016/j.jhazmat.2024.136762

Rivers are primary vectors of plastic debris to oceans, but sources, transport mechanisms, and fate of fluvial microplastics (<5 mm) remain poorly understood, impeding accurate predictions of microplastic flux, ecological risk and socio-economic impa...

Linear dynamics in turbulent stratified plane Poiseuille flow (2024)
Journal Article
Lloyd, C. J., & Dorrell, R. M. (2024). Linear dynamics in turbulent stratified plane Poiseuille flow. Journal of Fluid Mechanics, 999, Article A104. https://doi.org/10.1017/jfm.2024.1000

We investigate a turbulent stratified plane Poiseuille flow using linear models and nonlinear simulations. We propose the first complete explanation for the prolific and coherent backward (BWs)-and forward-propagating waves (FWs), which have been obs...

Benthic biology influences sedimentation in submarine channel bends: Coupling of biology, sedimentation and flow (2024)
Journal Article
Azpiroz-Zabala, M., Sumner, E. J., Cartigny, M. J., Peakall, J., Clare, M. A., Darby, S. E., Parsons, D. R., Dorrell, R. M., Özsoy, E., Tezcan, D., Wynn, R. B., & Johnson, J. (2024). Benthic biology influences sedimentation in submarine channel bends: Coupling of biology, sedimentation and flow. The Depositional Record, https://doi.org/10.1002/dep2.265

Submarine channels are key features for the transport of flow and nutrients into deep water. Previous studies of their morphology and channel evolution have treated these systems as abiotic, and therefore assume that physical processes are solely res...

Monopile-induced turbulence and sediment redistribution form visible wakes in offshore wind farms (2024)
Journal Article
Bailey, L. P., Dorrell, R. M., Kostakis, I., McKee, D., Parsons, D., Rees, J., Strong, J., Simmons, S., & Forster, R. (2024). Monopile-induced turbulence and sediment redistribution form visible wakes in offshore wind farms. Frontiers in Earth Science, 12, Article 1383726. https://doi.org/10.3389/feart.2024.1383726

Offshore wind farms are becoming an increasingly common feature in the marine environment as a renewable energy source. There is a growing body of evidence on the effects of wind farms on the seabed and its organisms. However, an important and unders...

Dynamics of microplastics particles in rivers: experimental settling processes and numerical models of the transport and deposition (2023)
Thesis
Barrantes, L. I. A. Dynamics of microplastics particles in rivers: experimental settling processes and numerical models of the transport and deposition. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4367345

Microplastic pollution is an environmental problem facing rivers, oceans, and coastlines. Estimations suggest that around 1.15 to 12.7 million tonnes of plastic waste enter the ocean every year from the global riverine system. In the environment, org...

Streamwise Turbulence Modulation in Non-Uniform Open-Channel Clay Suspension Flows (2023)
Journal Article
de Vet, M. G., Fernández, R., Baas, J. H., McCaffrey, W. D., & Dorrell, R. M. (2023). Streamwise Turbulence Modulation in Non-Uniform Open-Channel Clay Suspension Flows. Journal of Geophysical Research: Earth Surface, 128(8), Article e2022JF006781. https://doi.org/10.1029/2022JF006781

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...

Sedimentary bedforms such as ripples and dunes are generated both by river flows and sediment-laden gravity currents. Gravity current deposits are usually parameterized using existing bedform phase diagrams which are based on data from laboratory exp...
