Análise espacial para caracterização do potencial hidrogeológico de Vale do Sol, RS

Abstract

The application of digital information from indirect data such as Remote Sensing is an effective, low-cost and effective tool compared to traditional investigative work in the field. When associated with punctual and succinct direct information on the areas of interest, it offers important elements in a given area, adding quality, low cost and speed. The present work proposes to carry out a hydrogeological study using remote sensing data integrated with geological information in the county of Vale do Sol, state of Rio Grande do Sul. Specifically, it is intended to apply geoprocessing techniques, spatial analysis based on multiple criteria and field checks using indirect data on the density of lineaments, lithologies, soils, drainages and terrain characteristics such as slope. As a complement, direct data such as information from tubular wells and geology were used. From the use of specific software, generation of an integrated database, thematic maps and direct data of the area of interest, the results consist of an important addition to the knowledge about the hydrogeology of the county of Vale do Sol. They also help in the identification of areas potential and hydrogeological diagnosis on a regional scale. The integration and processing of the data served as support for the generation of a hydrogeological map with identification of domains (high, medium and low potential). This information consists of important elements in the allocation of wells, benefiting the local population and the county’s economy. Additionally, it provides managers and researchers with a useful methodological work routine to be applied in future work in similar areas.
