Collaborative tools for integrated management of a large river system: the Rhône river (France)

Résumé

The Rhône river is one of the main European alpine rivers (watershed: 98 500 km²; length: 812 km; mean annual discharge at its mouth: 1700 m3 s-1). The fluvial landscape has been engineered for more than 150 years (e.g., dykes, hydroelectric canals) leading to altered aquatic and riparian ecosystems. Today, stakeholders face tension in balancing various user interests regarding nature conservation, flood control, economic and recreational activities. In order to inform river managers and citizens, and to help environmental policies implementation, a collaborative and integrative science platform was established. The objective of the Human-Environment Observatory “Rhône Valley” (OHM VR, 2011) is to provide and share knowledge for improving river management practices, considering simultaneously public policies, human attitudes, biophysical and chemical dynamics. The purpose of this contribution is to present tools designated to centralize, structure, archive and share data produced within the different programs. We carry out a geographic database (~ 200 Go of data) containing GIS layers (e.g. LiDAR, aerial imagery, 18th-20th century georeferenced maps), and tabular and iconographic resources organized into a set of topics (topography, land use, etc.). A hydrological database is specifically dedicated to suspended particulate matter and their associated contaminants fluxes along the Rhône river and its tributaries (https://bdoh.irstea.fr). A geospatial metadata catalogue (http://elvis.ens-lyon.fr), built in respect to European and international metadata standards (INSPIRE, ISO 19139), provides technical information (e.g. spatio-temporal extent, genealogy, legal constraints). We also develop a web-GIS platform (http://mapmint.univ-st-etienne.fr/public/GeoOSR) allowing users to display geographic information (e.g. field measurements, alluvial margin restoration) and to look for data on specific reaches of the river continuum. These tools are the result of researchers’ and river managers’ collective and long-term investment. Sharing data can promote the emergence of new interdisciplinary research questions on the Rhône. A few examples are introduced to illustrate the use of such tools.
