The book launch for the 37th volume of the Cahiers de Vallesia—the fourth in the series dedicated to the Mémoires du Rhône conference—was held on 25 June at the Arsenaux in Sion. Entitled Le Rhône. Imaginaires, frontière et trait d’union, the volume brings together contributions from the two most recent conferences, including a chapter co-authored by Dr. Sara Formery, Dr. Martine Laprise, and Prof. Emmanuel Rey presenting the work carried out as part of the RHODANIE URBAINE project, initiated and developed by the Laboratory of Architecture and Sustainable Technologies (LAST).In an era of seeking new balances between rivers and the urban areas they cross, some sites are proving ideal for new sustainable river districts, particularly when they are connected to public transport networks and offer significant potential for urban regeneration. As a river that is undergoing significant changes linked to flood management, the Rhône is particularly emblematic of the many challenges inherent in these processes of transformation.In the chapter entitled Entre renouveau et continuité, imaginer des quartiers résilients pour la Rhodanie urbain, the authors present the development of specific project-based approaches to rhodanian neighborhoods in transition, as well as a range of tools for assessing the new city-river balance. To cope with the diversity of situations, the approach seeks to develop project-based visions on different study sites undergoing regeneration and showing evolution potential.Following the Rhône as a common thread, four study sites are selected, one for each hydraulic entity (excluding Lake Geneva and the Delta): a site in Sion located along the Rhône alpestre, a site in Geneva located along the Haut Rhône, a site in Givors (commune of Greater Lyon) located along the Rhône moyen, and a site in Avignon located along the Rhône inférieur.ReferencesSara Formery, Martine Laprise, Emmanuel Rey, « Entre renouveau et continuité, imaginer des quartiers résilients pour la Rhodanie urbain », in Le Rhône.
