A cheia de 2009 na Amazônia Brasileira

Abstract: Resumo O ano de 2009 se mostrou atípico do ponto de vista hidrológico em relação ao período e intensidade de cheia climatológica de alguns dos principais rios da Bacia Amazônica. Dentro desse contexto, busca-se, no presente estudo, entender como uma resposta heterogênea dos rios está relacionada com uma anomalia de precipitação de grande escala. Este trabalho apresenta uma análise da cheia de 2009 na Amazônia Brasileira com apoio em dados hidrometeorológicos. Para isso, foram utilizados dados de cota das estaç… Show more

“…The CPRM informed the public of early rains in western and central Amazonia in the summer of 2012, which determined early peak flows in the Tapajos and Acre Rivers, and later affected the levels of the Solimões and Amazonas Rivers. Besides the risk for the people living near the banks of the rivers, floods affect fishery activities and domestic agriculture due to the inundation of small farms (Marengo et al, , 2013a(Marengo et al, , 2013bVale et al, 2011;Sena et al, 2012;Satyamurty et al, 2013aSatyamurty et al, , 2013b. The river level at Manaus reached 29.87 m on May 2012, the highest mark in 110 years of stage data that started in 1902.…”

“…Past mega-droughts were registered in 1925-1926, 1982-1983due to El Niño (Tomasella et al, 2011Marengo and Espinoza, 2016). In contrast, "mega-floods" were detected in 2009, 2012, and 2014 (Chen et al, 2010;Vale et al, 2011;Marengo et al, 2012a,b;Sena et al, 2012;Coelho et al, 2013;Espinoza et al, 2013Espinoza et al, , 2014Satyamurty et al, 2013a,b) pointing to increased climate variability. Their observed impacts on natural and human systems in the region demonstrate the vulnerability of population and ecosystems to the occurrence of such hydro-meteorological extremes in the region.…”

“…Estudos apontam que as terrascaídas geram grandes impactos socioambientais aos ribeirinhos. Nos últimos dez anos, devido as grandes cheias, o processo de erosão se intensificou e atingiu muitas comunidades como, por exemplo, a comunidade de Fátima do Urucurituba, que teve cerca de 95% de suas terras levadas pela água, e a comunidade de Aninduba que teve grandes consequências durante a grande cheia do ano de 2009 (Vale et al, 2011) (Callede et al, 2002). As duas áreas de estudo apresentam uma unidade geomorfológica do tipo planície de inundação, as chamadas várzeas, que inundam periodicamente.…”
