A geomorfologia e o uso e cobertura da terra na Bacia Hidrográfica do Arroio Taquari-Miracatu, sudoeste do Rio Grande do Sul

Abstract

The present work aims to study, identify and compare land use and cover and geomorphological units in the Arroio Taquari-Miracatu Hydrographic Basin area over a period of time. The work identified the changes that occurred in relation to land use and coverage at small and/or large distances throughout the Basin territory. For this, files from the data layers were collected, which are provided by MapBiomas. After collecting this data, land use, land cover and geomorphological maps of the region were created with the characteristics of each type of vegetation. Thus, comparisons of changes were made, characterizations of the type of change that occurred in each area of ​​the Basin. These comparisons were made to identify and explain the changes that occurred, as they are not always a total loss of the type of vegetation, each loss of a type of vegetation gains another geomorphological unit, that is, the vegetation was not lost forever but rather lost. to another different neighboring vegetation, just as this space won another category. Therefore, the objective of the work was achieved, as the maps were created and consequently the changes could be identified and compared. This work also aims to serve as support for other research and to help with knowledge of the Arroio Taquari-Miracatu Hydrographic Basin area.
