Manival, le mauvais torrent - Episode 1 : des cailloux, des cailloux, encore des cailloux

#manival #torrent #flood "A torrent of water falling in the Manival region and causing an exceptional flood could cause a real disaster for an area of ​​1,500 hectares of the richest and most populated land in the Grésivaudan Valley." This is how forest inspector Charlery, head of the Isère reforestation service, described the risk posed by the Manival torrent in 1882. A source of concern during the 19th century for the communes of Saint-Ismier, Saint-Nazaire-les-Eymes, and Bernin, feared because of its multiple overflows on its cone, the Manival has since been subjected to human rule: that of torrential correction, erosion control, and Mountain Land Restoration. And it has now been nearly a century since the Manival has caused any damage to the homes and fields of the valley. Today, it's no longer frightening. It's part of the landscape. Yet the Manival is still active. Less bad perhaps, but alive, very much alive. And it's to learn more about it that we offer you this journey to the heart of a torrent unlike any other, yet so common, a journey to the heart of the Bad Torrent.
