description Vulnerability map is an effective tool to assess and identify the areas that are most susceptible to groundwater contamination, and can aid in the planning and management of municipal groundwater. These maps can help decision-making regarding land use and cover, pointing out proper sites to rural and/or urban sprawling but also highlighting restrictions for groundwater withdrawal. This paper aims at evaluating the influence of the lineament density (DRASTIC-LD) and the influence of the land use and cover, along with the lineament density, (DRASTIC-LDLU) in the classification of the vulnerability of the Serra Geral Aquifer System. The DRASTIC approach was modified by adding the lineament density. The DRASTIC-LD method showed high (70.73%), moderate (17.04%) and very high (12.17%) vulnerability. The DRASTIC-LDLU method presented high (55.35%), extreme (19.65%), very high (14.66%) and moderate (10.31%) vulnerability. Lineament density and land use and cover had a significant influence on the vulnerability classification. The spatial distribution of vulnerable zones was quite similar to those obtained by applying the original DRASTIC model. However, a significant increase in vulnerability was observed across the study area when the lineament density parameter was added, followed by an even greater vulnerability when the lineaments were inserted together with land use land cover. Inserting these two parameters together provides a more accurate result of vulnerability in fractured aquifers, as it is a more faithful representation of the reality of this system.

Os mapas de vulnerabilidade são uma ferramenta eficaz para avaliar e identificar as áreas mais suscetíveis à contaminação das águas subterrâneas, auxiliando no planejamento e gestão das águas subterrâneas municipais. Esses mapas podem ajudar na tomada de decisões sobre o uso e ocupação do solo, indicando locais adequados para expansão rural e/ou urbana, e também destacando as restrições para a retirada de água subterrânea. Este trabalho tem como objetivo avaliar a influência da inclusão do parâmetro densidade de lineamentos (DRASTIC-LD) e do uso e cobertura do solo, juntamente com a densidade de lineamentos (DRASTIC-LDLU), na classificação da vulnerabilidade à contaminação do Sistema Aquífero Serra Geral. O método DRASTIC-LD enquadrou 70,73% da área como de vulnerabilidade alta, 17,04% moderada e 12,17% muito alta. Já com método DRASTIC-LDLU, 55,35% da área foi classificada como de vulnerabilidade alta, 19,65% extrema, 14,66% muito alta e 10,31% moderada. A inserção dos parâmetros densidade de lineamento e uso e cobertura do solo apresentou influência significativa na classificação de vulnerabilidade. A distribuição espacial das zonas vulneráveis foi bastante semelhante àquelas obtidas pela aplicação do modelo DRASTIC original. No entanto, observou-se um aumento significativo da vulnerabilidade em toda a área de estudo quando foi inserido o parâmetro densidade de lineamentos, seguido de uma vulnerabilidade ainda maior quando os parâmetros densidade de lineamento em conjunto com o uso e cobertura do solo foram adicionados. A inserção desses dois parâmetros juntos fornece um resultado mais preciso da vulnerabilidade em aquíferos fraturados, pois é uma representação mais fiel da realidade deste sistema.ABAS - Associação Brasileira de Águas Subterrâneas2022-02-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://aguassubterraneas.abas.org/asubterraneas/article/view/3008610.14295/ras.v35i3.30086Águas Subterrâneas; v. 35 n. 3 (2021): REVISTA ÁGUAS SUBTERRÂNEAS; e-300862179-97840101-7004reponame:Águas Subterrâneas (São Paulo.
