Full textThe Rhône : a means to consider the world today. Local populations make us understand their own space, which creates a territory, legitimate boundaries which are those of local culture and which represent, now and again "another outline" compared to those officially recognised. They make us understand the passing of time, symbolised by the flowing river, telling their "native" stories. Social and cultural identities find their meaning in a historical inscription. Despite historical differences, from one bank to the other there can be a creation of solidarity, either through an exterior danger or a crisis (floods, the creation of a nature reserve). Such solidarity is not without certains tensions ; we do not become "brothers" with impunity, as here we have a same desir : to identify ourselves within the same boundary. How to create a territory, or rather how to become part of it, even when the boundaries are altered by man. This question is traversed by the idea of modernity. With our changing world, the economical, social, and cultural functions of the river, are not longer the same. The era of national or even international projets have taken the place of the "micro economy". Whole areas are arranged so as to be highly lucrative, or to enable leisure, sometimes they become landscapes for the largest number of people possible. In fact these spaces are everything except a territory

Full textLateral Erosion of the Sacramento River, California: Human influences and consequences for floodplain lake habitats This study is based on a spatial and temporal analysis of the active channel and associated flood plain lakes using aerial photographs spanning five decades (1942, 1962, 1985, 1999) over the entire 140 km long reach. Planimetric changes were analysed longitudinally (synchronic analysis) and temporally (diachronic) to highlight the spatial structures and their evolution through time. Revitalisation of Ht. Rhône and First Feedbacks on Revitalised Floodplain Lakes Sedimentation along the Rhône River The revitalisation work on Rhône River has been done on three different localities: Chautagne, Belley and Brégnier-Cordon. The morphologic form as a result of processes become consequently the control factor. Three steps were considered: i) to define the number connexions by year (the frequency of overbank connexion) ; ii) the measurement 1 of the sedimentation rates iii) the statistical analysis of the relationships and inter-lake analysis (the characterise of connexion frequency and to define the life expectancy of floodplain lakes). The diffèrent groups were defined by nPCA analysis. Morphodynamics of the Exit of a Cut-off Meander: Experimental Findings from Field and Labora tory Studies The morphological evolution of the entrances and exits of abandoned river channels govems their hydrological connectivity. The study focusses on flow and sediment dynamics in the exit of a cut-off meander where the downstream entrance Îs still connected to the main channel, but the upstream entrance is closed. Two similar field and laboratory cases were investigated using innovative velocimetry techniques (acoustic Doppler profiling, image analysis). Laboratory experiments were conducted with a mobile-bed physical model of the Morava river (Slovakia). Field measurements were performed in the exit of the Port-Galland cut-offmeander, Ain river (France)
