VARIABILITE SPATIO-TEMPORELLE ET DYNAMIQUE DES PLUIES DE FORTE INTENSITE A L'ORIGINE DES « CRUES RAPIDES » DANS LE BASSIN PARISIEN (FRANCE)

Abstract : Some “flash floods” with high suspended content affect at the end of spring and during the summer some parts of the Paris Basin, in north-western France, causing dramatic human and property damage: 269 events have been induced by 79 high rains between 1983 and 2005. Such events are the most dangerous form of floods encountered in this area because of their torrential nature. The aim of this study is to better assess the climatic conditions required to explain the genesis of such hydrological events in dry valleys, where normally no permanent stream flows exist. Two complementary data analysis are needed: i) a descriptive approach permits us to better understand the spatial and temporal variability of high rainfall intensities using critical thresholds on data providing from a network of 85 climatic stations; ii) using the European classification of Hess-Brewowsky, a more explicative approach led to identify the preferential circulations types linked to “flash floods” event. This approach should permit us to highlight the influence of climatic controlling factors and impacts of rainfall intensities inputs on the spatial and temporal occurrence of “flash floods”. Results should provide the necessary bases for a future suitable alarm system adapted to such hydrological risk.
