Surface runoff of the Bocamina post-industrial area in south-central Chile

The surface runoff sampling was conducted as part of campaign. On each date, automated runoff collectors positioned downslope of each treatment plot captured surface water and transported sediments to collection tanks.Sediment collected in bins. Before sampling the volume of water was thoroughly stirred and 1L Allicuots where sampled. The Allicuot was filtered and the sediment was oven-dry for 105°C until constant weight.
