| مستخلص: | Acid mine drainage with high levels of total iron (Fetotal) and trace elements still affects the rivers in the Kizel coal basin (Perm Region, Russia) 20 years after mining ceased. Sentinel-2 images from 2016 to 2019 have been used to estimate inter-annual and seasonal variability of AMD-related surface water contamination. The acid mine water index (AMWI) was calculated from the images and compared with measured Fetotal concentrations in the surface water. A statistically significant correlation between AMWI and Fetotal concentration was found for 5 out of 7 surface water sampling points. Surface water contamination reaches a seasonal maximum in July, 1-1.5 months after the end of the snowmelt high water period. Excessive summer rainfalls also contribute to increased contamination, possibly causing it to spread more than 200 km from the AMD sources. Arid summer conditions, however, were associated with a substantially decreased AMD discharge and Fetotal concentrations. The main uncertainties in the results are associated with the effect of contaminated bottom and bank sediments and suspended sediments on the spectral characteristics of the water surface, and the relatively coarse (10 m) spatial resolution of Sentinel-2 images. It is concluded that the results still show that Sentinel-2 images have substantial potential for monitoring AMD-related contamination of surface water.
