School of Geography, Earth and Environmental Sciences (Faculty of Science and Engineering)



I have a broad background in the geomorphology and hydrodynamics and have studied or worked in the academic sector for over 16 years. My principal interest is geomorphology, and I specialise in fluvial systems and sediment transport. I have authored multiple peer-reviewed articles, most recently on the transport dynamics of complex bio-mediated sediments, and regularly present at international conferences. My research work has spanned a range of experimental facilities and field environments and I have expertise in an array of specialist instruments for measuring flow & sediment properties. I have co-authored successful research grants including RCUK standard grants, the Higher Education Innovation Fund (HEIF) for innovative collaboration with industry, and for the development of novel instrumentation.

I have undertaken field-based research campaigns in the UK, Canada, Iceland and the High Arctic in rivers, lakes, estuaries, the littoral zone and glaciers. I have undertaken experiments in several of the UK’s principal hydrodynamics facilities including Plymouth’s COAST Lab, The Total Environment Simulator at Hull University, the Sorby Environmental Dynamics Laboratory at Leeds University and CEH Dorset’s Fluvarium. I specialise in physical modelling experiments and have previously undertaken scaled studies on sediment transport, flow around in-stream vegetation and the undermining of engineered structures through scour.

I have constantly sought to combine experimental rigour with innovation throughout my career and strongly believe in a multi-disciplinary approach to tackling contemporary environmental issues. Since arriving in Plymouth in 2009 I have forged links with different research groups across the University including biologists, geochemists, engineers, geologists and geographers. In addition, I have worked with the Plymouth Electron Microscope Centre to develop their ability to characterize complex sediments using microscopy.

I currently work for the Marine Institute leading a project that examines the potential for‘bio-seeding’ of sediment as an alternative to hard-engineering approaches to scour and erosion. This patent-protected technology takes a holistic approach that aims to simultaneously protect infrastructure and minimize the anthropogenic disturbance of natural habitats. The work encompasses multiple disciplines (structural engineering, hydraulics & sediment transport, the biology and ecology of benthic communities) which we are actively developing in partnership with environmental and commercial sectors. This exemplifies the real-world, problem-solving nature of my work. 



School of Geography, Earth and Environmental Science, Plymouth University (June 2018- )


I co-ordinate two related projects that focus on the mitigation of environmental hazards resultingfrom miningoperations. Both projects are supported by the Westcountry Rivers Trust (WRT) who area charity that work to protect and restore the rivers of the South West, primarily by promoting changes to land use that impact on water quality. WRT are involved in several initiatives to reduce sediment andcontamination from historic mining sites.


Biostablisation of Mining Spoil for Heathland Regeneration (with Sibelco UK)


Re-establishing heathland in former mining areas is problematic due to the losses of surface soil on treated slopes. Further, the loss of solid material from mine spoil in the Southwest contributes substantially to thesuspended sediment load in river catchments, reducing habitat function and light at channel boundaries. Mining spoil erodes rapidly as it is unconsolidated and devoidof microbes and vegetation that protects from wind, rain and frost, andstrengthens soil with roots and organic matter. 


We are working inconjunction with Sibelco UK and the Westcountry Rivers Trust to pioneer anovel, cost-effective and ecologicallysustainable method of stabilizing minewaste slopes.  This project, based at a trial slope at Sibelco's chinaclay (kaolin) mine at Lee Moor, Devon, was initiated in June 2018 and willrun for 12 months. The approach uses a natural biopolymerthat binds sediment particles together very efficiently to improve resistance to erosive forces.

Results will be used to inform future remediation of mining spoil and assist erosion prevention & re-vegetation efforts. In particular, fine sediments offer a mechanism to disperse potentially toxic elements(PTEs).  If successful, the proposed biostabilisation method can be applied to sites exhibiting toxicity to reducing further dispersal towater courses from which water is abstracted for domestic and agricultural purposes, and which may be remobilised from long-term storage by increasing storm frequency and sea level. 

From spoil heap to ocean: Metal pollutant partitioning in coastal catchments


The geology of the SW of England is rich in potentially toxic elements (PTEs) which arereleased through transport of particles and leaching into ground and surface waters. Over 90% of SW mining pollutant dispersal occurs in sediment-associated form, leading to the diffuse accumulation of metal-rich muds in rivers and estuaries since the Bronze Age.


Metals exist in two phases within a river’s discharge:

 (1) particulates adsorbed onto sediments or (2) dissolved in the water column. However,thereis no current understanding of the degree that metals adsorb onto muddy sediments. Because mud is only mobilized under certain flow conditions we hypothesize that the ratio of transported metals inparticulate vs. dissolved state varies dramatically in response to local hydrodynamics, principally because sediment is only mobile under certain flows and in certain locations.We will use laboratory flume experiments to determine how particulate metals will be released and transported in unsteady quantities as currents varywith weather and tidal conditions. 


The work will improve our ability to predict and monitor contaminant transport from source to sink.It is highly relevant to theaims of the WRT, EA and local government/conservationin meeting thestandards of the EU Water Framework Directive. Locally, it will inform important industries such as agriculture, mining, fisheries,aquaculture& marine engineers on the presence of metal contamination, and the impacts of bioavailability of metals in the local aquatic environment. Findings are applicable to all areas experiencing mining pollution, historically or contemporaneously.

Marine Institute,University of Plymouth (2015-6)

Marine Institute Research Fellow , HEIF-funded project, “Scour in Complex Cohesive Sediments”.

I secured funding from two rounds of the Higher Education Innovation Fund (HEIF) to initiate and develop a project with HR Wallingford that examines how scour dynamics are modified by physical and biological cohesion. The experiments address a significant flaw in current engineering guidelines and results will be integrated into existing guidelines.

I designed the experiments, acquired instrumentation, and undertook the experiments at Plymouth University's COAST Lab. In addition, I helped design, fabricate and retro-fit a sediment scour pit in the flume facility.

Furthermore, the results indicate that cohesive, bio-engineered sediments may have a new, previously unrecognised role in scour management.This has culminated in a patent application for this emerging technology and a forthcoming EPSRC standard grant proposal.

Specialist Technician, COAST Laboratory.

As specialist technician in one of Europe's most sophisticated ocean basin laboratories I worked first hand with scientists and engineers at the cutting-edge of coastal structure design and renewable energy devices. My role was split between teaching and consultancy. I worked with undergraduate, MSc & PhD students in the development of their research programmes, advised on experimental design, taught then specialized technique sand use of instrumentation, and mentored them during lab times.

I assisted visiting academics and commercial bookings in experimental design; deployed wave energy deviceS; installed scaled models & precision instrumentation, and; monitored data collection.

As a specialist in sediment transport I led the drive to re-configure the laboratory to better undertake sediment transport studies, ultimately culminating in the installation of a scour pit and collaborative projects with industry.

Research interests

My primary research interests centre around the flow properties of turbulent boundary layers and the resulting effects on sediment mobility and transport. My research can be divided into these areas.

  • Scour in complex, cohesive sediments
  • Bedform evolution in sand/mud channels 
  • The suspension and modification of particles in environments dominated by cohesive, flocculated sediments.
  • The modification of sediment transport and bedforms by benthic biota
  • The role of in-stream macrophytes in the modfication of 3D turbulence structure
  • Near-field dispersion in fluvial and near-shore lake environments over rough boundaries.

In addition, I am interested in the development of measurement of techniques including acoustic (ABS, ADV) and particle imaging techniques  (PIV, floc cameras) for the quantification of turbulence and sediment suspensions, and the development of signal processing techniques.

A multidisciplinary team from theUniversities of Bangor, Plymouth, Hull, St. Andrews with the NationalOceanographic Centre (Liverpool). We examined the physics, biology,sedimentology and mathematics of ripple and dune bedforms to investigate, forthe first time, key factors that control the behaviour and properties ofbedforms in mixed cohesive and non-cohesive environments: (i) System energy:effects of flow velocity, bed friction and flow depth; (ii) Bed properties:particle size, proportion of mud and sand, and biological effects, (iii) Time:the speed of bedform growth and rate of change as flow energy changes; (iv)Particle erosion: changes in the bedforms as smaller particles are eroded away.Experiments were undertaken in flume and field and include the development ofcutting-edge technologies, yielding several high-impact papers. The study wasguided by a numerical modelling committee and has yielded new parameterisationsand predictive capability.
