AB: This review seeks to examine connections between hydrology and biogeochemistry at the landscape scale. A review of research on landscape structure and organisation provides a context, and seeks to integrate work at relevant scales in ecology and geomorphology; the degree of connectivity between different landscape elements provides the key theme. Following a review of hillslope hydrology, links between runoff pathways and nutrient dynamics are then considered, with particular emphasis on riparian zones, where nutrient dynamics has direct relevance for water quality management in catchments. It is concluded that research needs to focus on the critical near-stream zone, given its importance in coupling hillslope and channel systems.
