Application of remote sensing and spatial analysis in geological alignments as an indicator of the potential for groundwater accumulation

The geological alignments represent fracture systems that allow the infiltration, percolation and accumulation of groundwater in crystalline terrains, originating the fractured aquifers. The exploitation of groundwater in these aquifers is conditioned to the fracture density of the crystalline rocks...

The exploitation of groundwater in these aquifers is conditioned to the fracture density of the crystalline rocks, as in the case of Agreste Sergipano. The objective of the present work was to identify areas suitable for the storage of groundwater through geological alignment spatialization to define the potential for groundwater accumulation in the fractured aquifers of Agreste Sergipano. The relief and drainage geological alignments were extracted in the Digital Elevation Model (DEM) and in the drainage network of the study area basins; and the consecutive spatialization of the densities of these alignments by the kernel interpolator. The application of this interpolator allowed the spatialization of five classes of lineation density, indicating the greater or less potential of underground water storage in the fractured aquifers of the watersheds in the Sergipe Agreste. It was concluded that the hydrographic basins of the Japaratuba, Sergipe and Vaza Barris rivers presented the greatest hydrogeological potentialities than the basins of the Piauí, Real and São Francisco rivers in the crystalline terrains of the study area. Os alinhamentos geológicos representam sistemas de fraturamento que possibilitam a infiltração, percolação e acumulação de águas subterrâneas em terrenos cristalinos, formando os aquíferos fraturados. A exploração de águas subterrâneas nestes aquíferos é condicionada à densidade de fraturamento das rochas cristalinas, como no caso do Agreste Sergipano. Dessa forma, o objetivo do presente trabalho foi identificar as áreas propícias ao armazenamento de águas subterrâneas através da espacialização dos alinhamentos geológicos, visando definir a potencialidade de acumulação de água subterrânea nos aquíferos fraturados do Agreste Sergipano. Foram extraídos os alinhamentos geológicos de relevo e drenagem no Modelo Digital de Elevação (MDE) e na rede de drenagem das bacias hidrográficas da área de estudo; e a consecutiva espacialização das densidades desses alinhamentos pelo interpolador Kernel. A aplicação desse interpolador possibilitou a espacialização de cinco classes de densidade de lineação, indicando a maior ou menor potencialidade de armazenamento de água subterrânea nos aquíferos fraturados das bacias hidrográficas no Agreste Sergipano. Concluiu-se que as bacias hidrográficas dos rios Japaratuba, Sergipe e Vaza Barris apresentaram as maiores potencialidades hídrogeológicas do que as bacias dos rios Piauí, Real e São Francisco nos terrenos cristalinos da área de estudo.
