During the last two centuries, France has been affected by severe floods, which are relatively well documented. The importance of these floods depends on their spatial extent and on their temporal dynamics. The flood of May-June 1856 is the largest one, covering almost two thirds of the total surface of France. This extreme flood results from the synchronized floods over the main french rivers : Loire, Rhône Garonne and upper Seine catchment (Yonne).The main objective of this work is to localize the different sources of information in order to gather and summarize the different studies conducted at the period of the flood. Then a statistical analysis of the rain and discharge measurements will be performed to quantify the extent and the dynamics of this event. By this way, its importance will be shown in comparison with other reference events over several basins, in terms of temporal and spatial scales.
