Morphological evolution of the Rhone River in the Martigny bend
Sustainable water management is a principal matter to ensure safety of waterways (Berga, 2016). In this framework, the correction of the Martigny bend is a priority measure of the 3rd Rhone River correction in Switzerland, which aims at increasing the flood protection in the region while ensuring sustainable conditions for the Rhone River (Arborino and Jordan, 2014). The project foresees widening the bed of the river to the regime width and lowering the bed in the bend (Saugy et al., 2022). A numerical model is built to represent the priority measure, in order to assess the impact of the project on the sediment transport capacity and the morphological evolution in the long term.
