Caracterização geomorfológica e do meio físico da folha Itapororoca 1:25.000.

This study aims to characterize the relief comprising Itapororoca Sheet (SB.25-Y-A-V-4-NO) 1:25.000, located in the Northeast region of Brazil. The results, obtained from the use of geoprocessing tools, preparation of topographic profiles, preparation of thematic maps and morphometric calculations, showed various geomorphological peculiarities of the terrain, allowing the detailing of the aspects: morphological, geological, standard of drainage network and performance of morphostructural and morphosculptural factors acting in the area. The terrain is part of the fold belt of Brasiliano cycle, in an area where it is possible to determine distinct geomorphological compartments, result of the interaction between the processes that operate in the relief’s modelling. The area is comprised of a stretch that covers the boundary zone between the sedimentary terrains and crystalline outcrop, where it is possible to visualize tiltings, tabular surfaces, staggered terrains, distinct valleys, rifting, ridges lines (medium and soft), anomalous drainage pattern, extremely straight channels, dendritic drainage basin and headwaters retreat, setting nuances typical of areas affected by transcurrent shear zones that are present on the substrate of Terreno Alto Pajeú (TAP), regional geologic unit where is situated the study area. Other physical aspects of the area are the forms of soil management, especially in the margins of BR 101, whose terrains of the L/W adjacencies are occupied by extensive monoculture of sugarcane, with stretches susceptible to the formation of ravines and gullies, damming of river channels and degradation of riparian forests.
