Conteúdo: 	Most of the Swiss floodplains of national importance are embanked. This paper describes the impacts of embankments built early this century on the soil and vegetation along a pre-alpine river. Embanking is responsible for selective retention of material (here calcareous alluvium). The variation in the quality and quantity of the alluvium is the main factor determining soil diversity. The morphological and the physicochemical properties of the soil are linked to original geomorphological position (island, old channel, distance from the embankment, etc.). The large variation in the soil is associated with a low diversity among the plant communities: from a phytosociological point of view, most of them no longer have the status of a floodplain community. Their isolation from the alluvial dynamics changes the physical conditions and speed of evolution of both the soil and the vegetation. This study shows the different kinetics of vegetation and soil following human impact.
