Morphometric analysis and geomorphological characterization of the Jaboatão river basin (BHRJ) – Pernambuco

Abstract

The design and morphometric characterization of a hydrographic basin are fundamental elements of the dynamics of this environment, enabling contributions in the planning and management of water resources. The hydrographic basin of the Jaboatão River is located in the South Forest of the state of Pernambuco, included in the group of small coastal basins. For its morphometric characterization the theoretical precepts of Tonello (2005) and the methodological procedures of Christofoletti (1980) were used, while for the geomorphological mapping the proposal of Demek (1972) was applied. The products achieved in the morphometric analysis were segmented in three criteria: geometric, relief and drainage network, some main results were: area, perimeter, coefficient of compactness, slope, river hierarchy, drainage density and channel length. In the geomorphological characterization, three morphostructural units and six geomorphological units were mapped for the study area. The results obtained from the morphometric indices and the geomorphological mapping, enabled an integrated analysis of the geomorphological landscape of the Jaboatão river basin.
