Evolution de l'Occupation des sols dans le bassin versant de la Seine depuis 1910 et ses conséquences sur la genèse des crues à Paris
Ingénieur Général du Génie rural, des Eaux et des Forêts, chargé du bassin Seine-Normandie
In this text, the author shows that the evolution of the modes of soil occupancy has little influence on the level of large floods affecting very extensive catchment basins. Exceptional rainfalls bring about saturation of soils and streaming is then maximum everywhere.
Since the historic flood of 1910 in Paris, the urbanization has developed chiefly on the extremity downstream of the Seine catchment basin, and very little upstream, where the flood is formed.
It is therefore possible to say that the urbanization which has developed up to this day on the Seine catchment basin would have little influence on the level of a flood similar to that of 1910 in Paris.
