Cartografia geomorfológica em bacia de 4° ordem na encosta do maciço de Mata Grande

Abstract

The dynamics of the landscape can be cartographically represented in geomorphology. In this analysis, geomorphological understanding is represented from larger compartments (Morphostructures) to smaller ones (Morphosculptures). In this sense, geomorphological mapping provides a more appropriate understanding, considering temporal contexts such as geological and hydrological factors. Thus, the classification of the relief reveals both endogenous and exogenous processes. It is worth noting the importance of applying morphometric indices such as roughness, slope, channel hierarchy, and lineaments. These indices allowed for a better perception of the study area. The methodological procedures of the International Association of Geomorphology, particularly the methods of Demek in 1972, were also, employed. Regarding the study area, in addition to the 4° order basin on the slopes of Mata Grande Massif, two larger hydrographic basins, Moxotó and Capiá, were considered. It is important to emphasize that the area is located in the Alagoas semi-arid region and should focus on the correct use of the soil to avoid degradation.
