Caracterização geomorfológica da microbacia hidrográfica do Riacho Grande da Cruz no Alto Sertão de Alagoas

Abstract

Geomorphology is a geoscience that tries to understand and explain the forms of relief, watershed is an area of the earth's surface, drained by a certain watercourse and peripherally limited by the watershed. In the microbasin, the use of remote sensing was extremely important to carry out the mapping, fieldwork also plays an important role as it leads the researcher to experience his research externally. The present work aims to study the hydrographic microbasin of the riacho grande da Cruz, it is part of the Talhada hydrographic region, the basin has 14,095 km2, throughout its territorial extension much of it is located in the municipality of Delmiro Gouveia - AL. Through a geomorphological mapping and a characterization of the basin, some results were obtained, such as the mapping of landscape units. In the methodology, a survey of bibliographic data was carried out with the use of geotechnologies: Qgis, Google Earth, gps applications and fieldwork, based on the research we were able to analyze the process of evolution of the use and occupation of the soil of the microbasin and also to find the geomorphological units, the research was important because from it we can direct paths for future works and even for the development of environmental projects.
