Storm events play a crucial role in controlling pollutant mobilization and transport in catchments. Concentration-discharge (C-Q) hysteresis analysis of storm events offers valuable insights into these processes and in linking results to pollutant sources and generating processes. This paper reviews the history and advances made by hysteresis studies, highlighting the recent integration of in-situ sensor/data-logging systems and quantitative hysteresis analysis. Recent years have witnessed a surge in C-Q hysteresis research, partly due to the expansion of use of in-situ sensors, enabling the collection of longer-duration and high-resolution discharge and water quality datasets covering a much greater number and range of storm events than previously possible. The paper then reviews developments in hysteresis description and classification, with a focus on quantitative hysteresis indices. Six indices are evaluated in terms of their strengths and weaknesses. Zuecco’s index emerges as an effective tool for quantifying C-Q hysteresis due to its systematic classification of hysteresis patterns and ability to assess figure-of-eight and complex patterns. Finally, the review explores the limited, but promising hysteresis research carried out to date in tropical regions, where it is argued such research has its greatest need and potential in exploring (and reducing) impacts of logging, land-use change and land management. |
