Rivers are integrators of spatially distributed pathways and processes that vary over timescales from seconds to decades. Changes to land use, climate, and contaminant loading rates are altering the structure and function of aquatic ecosystems across scales. Over the past decade, the wide-spread deployment of high-frequency in situ sensors for sediment, carbon and nutrient monitoring has revolutionized our understanding of watershed dynamics. These technologies have provided insight into export dynamics over diel, storm-event, and seasonal timescales and identified the disproportionate influence of short-term events on annual export and watershed function.

In this session, we welcome research that utilizes high frequency data to understand watershed processes and drivers of water quality across the aquatic continuum. We encourage submissions utilizing a wide range of methods, including hysteresis analysis, loadograph separation, and spectral decomposition, that unravel the pathways and processes of sediment and solute export from watersheds.
