	Research Interests
	The basic aim of my research is to understand and to gain further insight into the spatial and temporal variability of how catchments function and behave hydrologically at different scales; hydrological process linkages and the associated landscape controls. My work also involves the exploration of the inter-linkages between catchment hydrology and hydroecology and how the variability of hydrological behaviour of catchments and in-stream hydrology influences the structure and function of riverine habitats. These research objectives are integrated in the following research themes by close linkages: I. Catchment dynamics and hydrological behaviour: runoff generation and streamflow generation processes, flow paths: catchment inter-comparison; understanding landscape controls on hydrological flow paths and transit times of water in different catchments; conceptualisation of process understanding using Geographic Information Systems (GIS), landscape analysis and interpretation of environmental tracer data; use of tracer studies within modelling frameworks to understand catchment hydrological functioning; transit time proxies. II. Riverine ecosystems – ecologically meaningful hydrological/hydraulic assessment: understanding the hydraulic influences on feeding habitats of juvenile salmon and influence of stream flows on the migratory movement of adult salmon into tributaries used for spawning; exploring utility of the concept of connectivity, showing how it can contribute to a more interdisciplinary understanding of the effects of catchment-scale hydrological processes and the migratory movement of adult salmon (Salmo salar).
