The AVuPUR project (Assessing the Vulnerabiliy of Peri-Urbans Rivers): experimental set up, modelling strategy and first results

Le projet AVuPUR a pour objectif de progresser sur la comprehension et la modelisation des flux d'eau dans les bassins versants peri-urbains. Il s'agit plus particulierement de fournir des outils permettant de quantifier l'impact d'objets anthropiques tels que zones urbaines, routes, fosses sur les regimes hydrologiques des cours d'eau dans ces bassins. Cet article presente la strategie experimentale et de collecte de donnees mise en ½uvre dans le projet et les pistes proposees pour l'amelioration des outils de modelisation existants et le developpement d'outils novateurs. Enfin, nous presentons comment ces outils seront utilises pour simuler et quantifier l'impact des modifications d'occupation des sols et/ou du climat sur les regimes hydrologiques des bassins etudies. / The aim of the AVuPUR project is to enhance our understanding and modelling capacity of water fluxes within suburban watersheds. In particular, the objective is to deliver tools allowing to quantify the impact of anthropogenic elements such as urban areas, roads, ditches on the hydrological regime of suburban rivers. This paper presents the observation and data collection strategy set up by the project, and the directions for improving existing modelling tools or proposing innovative ones. Finally, we present how these tools will be used to simulate and quantify the impact of land use and climate changes on the hydrological regimes of the studied catchments.
