Research Interests

I am a fluvial geomorphologist and sedimentologist with established research interests in lotic ecology. My research combines field data collection, laboratory-based experimentation and numerical modelling at scales that range from the fluvial network to individual textural patches. There are two primary themes:

  • The physical processes at work in gravel-bed rivers and the sediments and landforms that they produce;

  • The role of fluvial processes in the provision, maintenance and functioning of freshwater ecosystems.

In addition to my work in the fluvial arena (sedimentary links, punctuated downstream fining, tributary significance and modelling) and on sediment sampling problems (automated photographic methods, hybrid subsurface sampling, bootstrap sampling criteria), I have developed innovative work at the interface of geomorphology and ecology (hydrodynamics of the benthiscape, the Link Discontinuity Concept, geomorphological habitat genesis).

Current projects

 

 

 

Impact of freshwater fauna on grain structures and sediment transport in gravel-bed rivers

 

This work is ongoing and mainly has been carried out with Matthew Johnson and Andrew Pledger. To date we have examined the role of net-spinning caddis fly larvae (hydropsychidae) in stabilising fine-grained sediment patches and the role of signal crayfish in destabilising gravelly sediments.  Andy is currently using a large outdoor flume to examine the impact of barbel on gravel transport. Matt is Post-doc RA on an EC-funded grant to develop protocols for incorporating ecological elements in physical hydraulic modelling.

 

Structural development of coarse-grained fluvial sediments

 

This NERC-funded work is based in Loughborough, Leicester and City Universities. Dr Annie Ockleford is the RA working on a series of flume experiments at Loughborough to examine how sediment grade, sediment supply characteristics and hydrograph shape affect the development of surface structures in gravel-bed rivers. The work incorporates unusual laser scanning technologies to capture 3d surface DEMs and colleagues from Leicester and City are developing novel elevation modelling and pattern recognition algorithms to establish sensitive, quantitative measures of structural development.

 

Fluvial geomorphology and controls on water temperature variations in the Dove Catchment, UK

 

The funded part of this research (a Fluvial Audit of the upper Dove catchment as part of DEFRAs Catchment Sensitive Farming Initiative) is complete. With RA Dr Julia Toone and Prof. Rob Wilby, we are continuing to work on sediment characteristics, suspended sediment mobility and the catchment-scale controls on water temperature variations along the Rivers Dove and Manifold. We are currently monitoring water and air temperatures at approximately 100 sites along the two rivers.

 

Sedimentology, ecology and geomorphology of compound gravel bars, Fraser River, B.C. (Royal Society, NSERC)

The genesis and development of compound bars in gravel-bed rivers is of significant sedimentological interest. The bars under examination here are additionally important because they are the local expression of anthropogenically accelerated paraglacial aggradation, with implications for the provision of salmonid habitat and flood hazard management on a river of global ecological significance.


Hydrodynamics and macroinvertebrate use of river-bed sediment patches

Experimental investigation of the relations between the texture of sediment patches, benthic hydraulic habitat and the provision of refugia for macroinvertebrates during disturbances.

Modelling the impacts of sediment inputs and their ecological implications along gravel-bed rivers

Many river attributes are disrupted at tributary junctions and other lateral sediment sources (e.g. landslides) but our ability to predict those impacts is, at best, rudimentary. This project has developed and is testing 1-D sediment routing models that will, for the first time, provide quantitative predictions of how lateral sediment sources affect recipient channels. Two papers have been published and two papers are in preparation.
