Short summary

Open-cast mining increases soil erosion and transfer of sediment in river systems. Providing a methodology to better understand the sediment dynamic of these catchments is essential to manage this pollution. In this study, different tracers such as elemental geochemistry or colour properties were tested to trace and quantify the mining source contributions to the sediment inputs in the Thio River catchment, one of the first areas exploited for nickel mining in New Caledonia (i.e. since 1880).
