Biography

My research is focused primarily upon the dynamic and complex relationship within rivers between the processes that generate and supply fine sediment, and those that move the sediment through the river system. In recent years it has become increasingly apparent that fine sediment is a key factor in the environmental quality of a river system, as it plays an important role in determining the nature and rate of transport of nutrients and contaminants. Hence, the understanding of possible sources, pathways and fates of fine sediment is now recognised as an important element of water resource management. Within this framework my research has three broad themes: (1) spatial variations in runoff and sediment transfer, including the pathways that runoff and sediment follow (hydrological connectivity); (2) the supply of sediment from gullies and bank erosion; and (3) practices of undertaking interdisciplinary research to bring together the scientific outputs from the natural sciences with those of social sciences.

1) Spatial variations in runoff and sediment transfer
My research on the spatial variation in runoff and sediment transfer is conducted in both semi-arid and temperate environments. This research, which has involved detailed field monitoring and laboratory analyses, has allowed a new level of quantification of the rates at which sediment enters and moves through the evolving gully system, and has permitted the development of new models to understand the processes through which sediment delivery and transport occur.

2) The supply of sediment from gullies and bank erosion
The supply of sediment from gullies in semi-arid environments is important because many arid areas appear to be entering a new phase of dynamism. My research on this topic has helped in determining and defining the factors that control the generation of gullies, and in determining the response of gullies in terms of morphology and channel-form to environmental perturbations. My research on bank erosion as a sediment source was has helped to quantify the volume of material added by river channel instability.

3) Practices of undertaking interdisciplinary research
This research theme focuses on the development of an interdisciplinary framework for the investigation of earth surface systems. This work is critically important because it utilises a holistic approach that draws upon the skills and practices from different disciplines to produce new levels of understanding of problems facing the global community, most notably the impact of policy and anthropogenic behaviour on environmental processes.
