Acesso em:.https://repositorio.ufpa.br/handle/2011/7905The aim of this study was to analyze the behavior of precipitation and flow in two river regions of the state of Pará, where Northern Corridor and Coast Northeast Atlantic. Both have the same rainfall and physical properties of the bowls are similar, being different only in regard to level and vegetable preservation area. For this study, we used 7 gauged stations and 7 rainfall in the Northern Corridor and 6 fluviometric 6 and rainfall in Costa Northeast Atlantic. After collecting the data in HIDROWEB, they were organized in Microsoft Excel spreadsheets software for application of Mann Kendall and Spearman tests, which stated that there is no trend in the series analyzed (α=5%). Was detected that the density of fluviometric and rainfall stations is low , according to the thresholds established by WMO. The Pearson correlation coefficients showed up "strong" between precipitation and flow of the areas studied, which also suffer influence of climatic phenomena (El Niño and La Niña). It was possible to consider that in the most preserved region, the time lag between the maximum rainfall and the maximum flow rate averaged two months, while the region with greater human action this time was an average of 1 month.Acesso AbertoChuvasVazãoMedidores de fluxoBacias hidrográficasAmazônia brasileiraRainFlow rateFlow metersWatershedsBrazilian AmazonAnálise do comportamento da precipitação e da vazão em bacias hidrográficas AmazônicasAnalysis of the behavior of precipitation and flow in Amazonian hydrographic basinsDissertaçãoCNPQ::ENGENHARIAS
