Análise dos níveis de água subterrânea e considerações dos parâmetros hidrogeológicos e hidrometeorológicos na Folha 17, Nova Marabá, Marabá-Pa

Abstract

In this work, groundwater levels and their hydrogeological and hydro-meteorological parameters were analyzed in Folha 17, Nova Marabá, Marabá-PA, which is part of the geological context of the fissural aquifer and Couto Magalhães formation. Among the analyzed parameters are: depths of groundwater levels in periods of high and low rainfall; geology; climate; hydrography; soil; vegetation; topography; brittle structures and geomorphological picture of a the study area. It was verified the direct relation of the pluviometric and fluviométricos levels in the variation of the underground water levels, average estimate of up to 8 meters in the variation of the depths obtained in distinct periods, as well as the importance of the vegetal cover, differential parameter of the area in relation to the urban zones surrounding. The quantitative interpretation of the data considers groundwater levels in Sheet 17 to be relatively shallow compared to the levels of other areas under similar conditions of relief and topography, due to the conserved vegetal and arboreal cover, associated to the degraded lithology to more superficial levels and less thick eluvial coverings.
