Impact of the Amazon tributaries on major flood in Óbidos
Résumé
Major flood of the Amazon river (with discharge over 250 000 m 3 s-1) is analysed, using daily discharge at a) Óbidos, the last gauged station of the Amazon river, 800 km from the ocean, b) six gauge stations located on the main tributaries and characterized by different discharge regimes. During the 1984-2001 period major flood on the main stream is related to the following features: a) greater than usual high water in the Solimões river, the greatest tributary, b) delayed discharge peaks in the southwestern tributaries and in the Amazonas river (Peru) and/or advanced discharge
