Geotechnology Applied to the Environmental Analysis of the Olho d’Água River Watershed, Municipality of Jardim, Mato Grosso do Sul - Brazil

The preservation of natural resources is essential to the balance of Environmental systems. Water is an indispensable natural resource for life. In order to implement the environmental management of this resource, the National Water Resources Policy was created based on some principles, such as the adoption of the watershed as a planning unit. The use of geotechnologies constitutes an important tool for this work, since it allows evaluating the area to be studied, to visualize the situation of the vegetation cover and the soil, besides attaching them to georeferenced databases. The objective of this work is the environmental analysis of the Olho D’Água River Watershed, located in the Municipality of Jardim, State of Mato Grosso do Sul. For the delimitation of this watershed, SRTM data were used and with the objective of evaluating the quality of the coverage of this area, the NDVI was calculated based on the scenes of Landstat TM sensor. Subsequently, the classes of Permanent Preservation Area were analyzed. It was concluded that the conservation status of Permanent Preservation Area is in compliance with environmental legislation, fulfilling its role in maintaining biodiversity and the quality of water resources. The use of geotechnologies allowed the integration of various levels of information, generating maps, characterizing the environment and producing information that helps in the planning and management of Cabeceira do Prata Farm.
