		<abstract>O objetivo deste estudo é entender como o derretimento das geleiras tropicais dos Andes influenciam na disponibilidade hídrica na Bacia do rio Madeira, particularmente durante os eventos El Niño. Foram analisados, no período de 1985-2014 (30 anos), os níveis de água de um rio da bacia Amazônica abastecido (Rio Madeira) pelas geleiras e a variação da precipitação da mesma bacia. As mudanças nas geleiras foram compiladas desde 1980 a partir de dados da literatura realizados por imagens de satélite. Os resultados indicam a importância das geleiras andinas tropicais da Bolívia e do Peru na hidrologia da Bacia do rio Madeira. As análises deste rio indicaram que mesmo quando a precipitação diminuiu (Maio-Outubro) o nível do água não baixou, essa observação foi comum quando ocorreram eventos de El Niño e durante a fase positiva de ODP. ABSTRACT: The main objective of this study is to understand how the retreat of glaciers in the tropical Andes influences the hydrology in the Amazon Basin, particularly during El Niño events. We analysed water levels from two Brazilian rivers in the Amazon basin, of which one is glacially fed (Madeira River) and the other one (Envira River) is not, precipitation data near these two rivers were also analysed, for the 1985-2014 period (30 years). The changes in glacier surface since the early 1980s were compiled from the literature. The results indicate the importance of tropical Andean glaciers in the Eastern Cordillera of Bolivia and Peru in the hydrology of Madeira river. Analysis of the Madeira River indicated some years were associated with higher water levels even when the precipitation remained low during the corresponding season (May-October). This observation was common when El Niño events occurred during the positive phase of PDO.</abstract>
