A Multiparameter and Multiscale Dataset to Study Sediments and Particle-Bound Pesticide Dynamics of Hydric Transfers in a Wine-Dominated Catchment

Abstract

Sediment transport plays a crucial role in water quality at the catchment scale. Yet, access to comprehensive datasets for research on sediment quantity and quality at different spatial scales remains limited. This paper introduces a comprehensive hydro-sedimentological dataset on the Ardières-Morcille catchment and scientific observatory (Beaujolais vineyard, France) available for the period 2020–2023. The observatory was monitored at three nested scales: the Saint-Joseph plot (0.28 ha), the Morcille sub-catchment (3.9 km²), and the Ardières catchment (143 km²). This dataset includes continuous monitoring of rainfall, water level, and turbidity at the three sites, from which discharge and suspended solids concentrations are derived. In addition, discontinuous yet integrated over time samples were collected for SPM grain size, major elements, and particle-bound pesticides analysis. This dataset has made it possible to assess orders of magnitude for sediment and particle-bound pesticides transfers and to interpret scale effects in time and space responsible for these transfers. We expect this dataset to be a valuable resource for the research community, supporting investigations into sediment transport processes, contaminant fluxes, and hydrological dynamics across multiple scales.
