The dry beach length determines the hydraulic boundary of tailings impoundments and significantly impacts infiltration line, which is crucial for dam. A deep learning method utilizing satellite images presented to recognize area accurately measure beaches in tailing ponds. Firstly, various ponds were gathered collection was enlarged create a dataset Then, created using YOLOv5-seg identify from images. mask region segmented contour extraction then carried out. Finally, crest line fitted based on extracted contour. pixel distance between measured translated into real by ground resolution. This paper’s case study compared calculated with obtained field monitoring. results showed that minimum error 2.10%, maximum 3.46%, average 2.70%, indicating high precision calculating

The deposits of mine tailings can be a source groundwater contamination by metals. In this study, we simulated the concentrations iron, manganese and aluminum in potentially affected drainage from located Brumadinho (Brazil). aim was to verify whether observed region attributed these drainages. simulation used FREEWAT graphical interface, which incorporates MODFLOW model, hydraulic properties existing unconfined confined aquifers, spatial distribution tailings' deposits, dissolved iron measured drilled wells. period 20 years, starting 2019 after collapse B1 dam Córrego do Feijão Vale, S.A. modeling results revealed plumes metal progressively less dispersed over time, aquifer, increased aquifer. both aquifers were generally lower than legal limits imposed for human consumption, although some areas vicinity had higher those limits, especially widened time. most relevant result revelation that contribution wells might have not exceeded 1%. This is important management standpoint, because monitoring anthropogenic cases (where rock weathering dominates chemistry) becomes more challenging.

The Soil and Water Assessment Tool (SWAT) was used to assess total phosphorus concentrations (TOT-P) fluxes (TOT_P) in the Paraopeba River basin, located state of Minas Gerais, Brazil, following collapse tailings dam B1 Brumadinho. model calibrated validated for periods before (2000–2018) after (2019–2021) Brumadinho 25 January 2019, with great accuracy measured by various performance indicators (e.g., R2 ≈ 0.8). flow phosphorus-containing sludge from iron-ore explored Córrego do Feijão Mine Vale, SA, released break has impacted water through large increments TOT-P near site (60–100%, pre-rupture values varying between 0.06 0.1 mg/L). But other major sources were flagged, namely urban Betim region that raised 0.9 mg/L periodically during entire simulation period. study also revealed controls concentration coverage forests lowered down at 0.5–0.8 μg/L.km2. lowering rate was, however, dependent on occupation argisols. As per results, larger percentage argisols a will be surrounding courses, meaning are prone erosion leaching.
