| In this research we present a comparison between flood impacts, flow data and rainfall data at regional scale (Catalonia, NW Mediterranean). From a bottom-up approach, a statistical methodology has been built in order to identify quantitative thresholds that will make possible to classify floods from an objective point of view. The purpose of this study is to establish generic thresholds for the whole Catalan region. To achieve this objective, maximum daily rainfall, daily flow and its return period have been analyzed for each flood event relating them to flood categories by boxplot diagrams. Flood categories have been built considering the severity of the flood impacts (Llasat et al, 2014): extraordinary - CAT 1, catastrophic - CAT 2 and major catastrophic ? CAT 3. We also present a detailed analysis of the relations between flooding episodes, flood classification and weather type schemes - based on Jenkinson and Collison classification (Jenkinson and Collison, 1977). This classification allows analyzing the most frequent weather patterns associated with flood events in Catalonia. | |
