Mise en place d'une méthode d'identification des potentielles sources de matières en suspension d'un bassin versant : application au bassin versant du Rhône

Abstract : Suspended particles beget sanitary, ecological and economic issues on the Rhône River, the main issue being the fact that they carry pollutants such as polychlorinated biphenyl (PCB) and mercury. In order to study the transportation of those pollutants, it is necessary to identify which areas are sensitive to water erosion and thus could produce wide amounts of suspended particles. The production of suspended sediments is driven by geology, geomorphology, pedology, anthropisation and climate. The aim of this research is to build and apply a spatial analysis method, which would lead to the identification of the potential sources of suspended matters within the wide watershed the Rhône watershed is. The spatial analysis shall be a Hierarchical multicriteria analysis coupled with a Geographic Information System (GIS). The weighting method used in this research is an Analytic Hierarchy Process (AHP). The validation of the results lies on quantitative data: suspended material flows from stations and sediment export assessed on two subwatersheds from sediment transfer.
