Sytuacja początkowa
End of January 2021, the metropolitan area of Santiago endured heavy rainfalls of more than 116 mm. A phenomenon that had not occurred since 1933. This, plus the scarce vegetation in the mountains and a zero isotherm above 3,500 meters, activated several streams and gullies.
In the commune of Lo Barnechea the water affected homes, streets, roads, and infrastructure and caused emergency works.
