The Miribel Canal, embanked from 1848 to 1857, is the oldest development scheme of the Rhône upstream Lyon. Since 1937, the Jons dam controls the discharge and provides a 30 cumecs minimum flow. The study deals with the relations between the long profile adjustment over a period of 130 years, the surficial bed granulometry and the flood hydrology. The archives of the Service de la Navigation du Rhône and the surveys of the Compagnie Nationale du Rhône document precisely the long profile changes. The granulometry has been surveyed along a 17 km section, using a size measurement method ; a large amount of the gravelly bed material is presently reworked by floods ; over the bars the sediment size decreases downstream due to hydraulic sorting, but the vertical incision of the river bed has provokedthe exhumation of coarse deposits of fluvioglacial and morainic origin. Currently, this material is stable and controls the long profile of the Miribel Canal. Source : Éditeur (via Persée) |
