Tailings storage facilities flood exposure assessment using a <scp>2D</scp> hydrodynamic model

Abstract Minimizing environmental pollution from Tailings Storage Facilities (TSFs) is one of the key goals mining sector. While much attention given to risks potential catastrophic failures large TSFs, there also a need assess due noncatastrophic but more frequent releases contaminants. In response this need, article proposes method for prioritizing TSFs in terms flood exposure, based on maps produced by Shallow Water Integrated Flood Tool. The was implemented using case study event Copiapó city region (Atacama, Chile). A sensitivity analysis carried out evaluate influence different model configurations and input parameters. results showed that 10% all were exposed waters fluvial dynamics Copiapo River. Additionally, revealed extreme local precipitation, capable generating runoff, up 88% could have some degree exposure. suggest simulations satellite‐derived terrain data at moderate resolution can be used preliminary large‐scale assessment TSF
