The results of 10 years of daily observations of the flux of suspended matter in one of the main watercourses in the European Alps: The Isere at Grenoble (France)

Despite being only a medium-sized tributary of the Rhone, contributing on average 11% of the latterʼs annual flow, the Isere River nevertheless plays a major role in the Rhoneʼs flux of suspended matter (SM). However, the transit of suspended matter down the Isere has been little studied. Based on regular and continuous observations between January 1995 and December 2005, the aims of this study were to quantify the flux of the Isere at Grenoble, and to evaluate the monthly evolution of sedimentary transit since 1960. The mean annual flux over the last few decades is thus estimated at 1.76Mtyr-1.

Si l'Isère est un affluent relativement modeste du Rhône de par sa contribution aux écoulements (11% en moyenne de l'écoulement annuel du Rhône), elle joue cependant un rôle essentiel dans les flux de matières en suspension (MES) de ce fleuve. Pour autant, le transit de matières en suspension de l'Isère reste encore l'objet de très peu d'études. À partir de relevés réguliers et continus, depuis janvier 1995 jusqu'à décembre 2005, l'objectif de cette étude est donc de quantifier les flux de l'Isère à Grenoble, et d'apprécier, au pas de temps mensuel, l'évolution de ces transits sédimentaires depuis 1960. Pour ces dernières décennies, le flux annuel moyen est ainsi évalué à 1,76Mtan-1.
