Abstract
Hydrograph separation studies during the 1960s, 70s and 80s (conducted initially using geochemical tracers and later using environmental isotopes) prompted a paradigm shift in our view of stormflow generation at the catchment scale. However, the widespread revision of our concepts of catchment-scale runoff processes that was anticipated in some quarters has been tempered by, among other things, resistance to incorporate hydrograph separation results into catchment-scale hydrological models and increasing recognition of the limitations and uncertainties associated with hydrograph separation studies. There is almost universal agreement today that tracers (both reactive and non-reactive) need to be combined with hydrometric measurements to study hydrological and hydrochemical processes at the sub-catchment and catchment scales. Examples of studies where evidence from tracer, isotopic and hydrometric methods has been effectively reconciled will be reviewed, and some of the methodological and conceptual challenges facing the application of such integrated methods to the study of catchment hydrology and hydrochemistry will be discussed.
