Análise de vulnerabilidade do aquífero Barreiras a partir de dados hidrogeofísicos - área adjacente ao bairro de Emaús, Parnamirim-RN. 2019. 60f.

Universidade Federal do Rio Grande do Norte, Natal, 2019.https://repositorio.ufrn.br/handle/123456789/34335This present study has been developed in Pirangi River basin, more precisely in the middle course of Pitimbu River, located in the surroundings of Emaús neighborhood, Parnamirim-RN. The Barreiras Aquifer, which is the main subject of this research, is a source of water supply for most of the cities in the east coast of Rio Grande do Norte state, including the metropolitan region of Natal. However, its predominant regional hydraulic condition is free or semi-confined, which may indicate a risk of being affected by contaminants occasionally discarded on its surface. Thus, in order to support studies under such a perspective, efforts have been made in order to analyze the degrees of intrinsic vulnerability of the Barreiras Aquifer, that is, in the reported area, thus considering hydro-geophysical data. In such a context, it has been used GOD vulnerability analysis methodology, which considers local hydraulic conditions (parameter “D”), geological composition of substrates (parameter “O”) and unsaturated zone thickness (parameter “D”). However, considering that such a methodology data, it was necessary to adapt the method for a compound version, i.e. information from well profiles and Vertical Electric Sounding-VES models inversion. Therefore, the geoelectrical model representative of each VES has assumed the role of a “virtual” well, providing GOD parameter information in subareas where well information was missing. Additionally, the GOD map was corroborated by two other cartographies, both of them with emphasis on the unsaturated zone overlying the aquifer, particularly thickness and longitudinal conductance (S), being the latter based solely upon VES models inversion. Generally speaking, the greater thickness of the unsaturated zone and areas with higher values of “S” showed a higher degree of protection of the aquifer, in line with GOD cartography. The latter, by its turn, showed vulnerability degrees that ranged from 0,35 to 0,42 in the eastern and northeastern sectors, comprised of the relatively less vulnerable regions in the investigated area, standing out around the locations around VES 1 and VES2, as well as around wells PT01 and PT03. The central-north and central-south subareas presented the highest rates, ranging from 0,46 to 0,52, representing those relatively more vulnerable to contamination, with the largest anomalies around VES3, VES4 and also well PT02. Such a context projects a Barrier Aquifer GOD vulnerability in the investigated area, which ranges from moderate to high.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/aquífero BarreirasBarreiras aquifervulnerabilidade GODGOD vulnerabilityhidrogeofísicahydrogeophisicscondutância longitudinal, .longitudinal conductanceParnamirim-RNbachelorThesis
