Caractérisation des échanges nappe-rivière : de l'approche scientifique à l'outil opérationnel Characterization of the interaction between surface water and groundwater: a scientific practical guidebook

This paper presents the process of building operational tools in the field of water management: methodological and technical guidebooks for the characterization of groundwater/river interactions. The first part of the process was based on scientific work. The aim was to develop and refine an interdisciplinary methodology to assess synthetically groundwater/river exchanges. This methodology involved different approaches: hydrology, geomatic, mathematical modeling, ecology and geochemistry. The second part of the process was based on cooperative work, between scientists and technicians, managers or stakeholders to build methodological and technical guidebooks.
