Modeling of floodable areas in a mining sector of the Arrayan Basin - Coquimbo Region - Chile.

The Arrayan basin is in the Coquimbo region of northern Chile. It is an area of intense mining activity for copper and gold extraction, and for the numerous tailings dams installed in the urban area west of the basin. There are 108 tailings dams in the western sector of the basin, most of them aband...

description The Arrayan basin is in the Coquimbo region of northern Chile. It is an area of intense mining activity for copper and gold extraction, and for the numerous tailings dams installed in the urban area west of the basin. There are 108 tailings dams in the western sector of the basin, most of them abandoned or inactive. The western sector of the basin is an area susceptible to flooding, with floods occurring in 1997, 2015, 2017 and 2020. The semi-arid climate with rainfall concentrated in a few days, combined with mountain depression sectors, such as the undulating plain to the west of the basin, are factors that contribute to the susceptibility to flooding in the study area. Water dynamics in areas with a concentration of abandoned tailings dams may represent a potential aggravation of the risk, considering the entrainment of heavy metals and water and soil contamination. As a result, through mathematical modeling in GIS, it was identified that 63% of the abandoned tailings dams are in flood zones and close to populated areas.

La cuenca hidrográfica Quebrada del Arrayán, se encuentra ubicada en la región de Coquimbo, al norte de Chile. Es una zona reconocida por la intensa actividad minera de extracción de cobre y oro, y por los inúmeros tranques de relaves instalados en los alrededores de la zona urbana a oeste de la cuenca. Existen 108 tranques de relaves instalados en el sector oeste de la cuenca, la mayoría de ellos en estado de abandono o inactividad. El sector oeste de la cuenca es un área susceptible a inundaciones, destacando las ocurridas en 1997, 2015, 2017 y 2020. El clima semiárido con régimen de precipitaciones concentradas en pocos días, combinado con sectores de depresión en montaña, como la pampa ondulada y los cordones transversales, son factores que contribuyen con la susceptibilidad de inundación en el área de estudio. La dinámica hídrica en zonas con concentración de numerosos tranques de relaves abandonados puede representar un agravamiento potencial del riesgo, considerando el arrastre de metales pesados y la contaminación del agua y suelo. Como resultado, por medio de modelación matemática en SIG se identificó que 63% de los tranques de relaves abandonados se encuentran instalados en zonas inundables y cercanos a sectores poblados.
