Biography

I am a fluvial geomorphologist and sedimentologist, specialising in ecogeomorphology: the physical processes at work in gravel-bed rivers, the sediments and morphologies that those processes produce, and the two-way interactions with freshwater ecological process and patterns. Asking and answering questions in these arenas matters for developing a better understanding of how rivers work and for managing river ecosystems more effectively. Within these themes, recent and current research follows four strands.

  • Ecogeomorphology and freshwater zoogeomorphology - how fish and invertebrates, like crayfish and barbel, affect fluvial sediment transport processes, including work with the Environment Agency, Barbel Society and EC Hydralab IV consortium.
  • The structure and size characteristics of gravelly, river-bed sediments - recent (NERC) flume experiments have focused on the temporal evolution of bed material texture and how bed load intensity, sediment sorting and hydrograph shape affect the development of imbrication and other gravelly, bed structures.
  • The sedimentology, geomorphology and eco-hydraulics of gravel-bed rivers at patch and bar scales, including work on Fraser River, Canada.
  • The routing of sediment through river networks and the role of “sedimentary links” in structuring and explaining fluvial sediments and ecosystems, including work in the UK Peak District for Natural England.
