| Summary: | The proposed study is based on an analysis of rainfall variability and flood over more than half a century (1947-2014) in two countries in Sahel (Mauritania and Senegal). The rain analysis is based on the use of the chronological graphic method of information processing (MGCTI) of „Matrice Bertin” type. Applied to rainfall-relayed data, this method allows, in a first stage, the analysis of the spatiotemporal distribution of the meteorological parameter, then, in a second stage, the determination of data on cycle changes, if there are manifest cyclic, due to the regional analysis. The results demonstrate that at the end of the Sahelian climatic drought and a return of rains confirmed over the last decade of the studied period (1947-2014).
