- Abstract
In a semi-arid climatic context, the demand for water resources is a limiting factor for the quality of society life, so research that focuses on the understanding of semiarid river dynamics is fundamental for planning/management and coexistence in drylands. Thus, the present work analyzed an Ipanema River, located in the states of Pernambuco and Alagoas, with the objective of adapting the methodological proposal of fluvial styles to analyze the local morphodynamics associated to semiarid drainage. For this purpose, a Digital Terrain Model (SRTM) was used as an analysis tool for automatic extraction of the drainage basin; and Google Earth Pro georeferenced images for the processing of maps in GIS environment with emphasis on the identification of erosive and depositional forms; fieldwork and application of technical file for evaluation of fluvial processes. The section under analysis refers to the canal with confined space partially confined, with discontinuous water flow, anastomosed pattern, with the presence of deposits in isolated longitudinal bars, pontoon bars, discontinuous flood plains and marginal dikes, besides erosive processes, such as margin overlap. The detailed study of dryland fluvial channels has a relevant social utility, considering the possibility as an alternative to the planning and management of water and environmental resources in an integrative and efficient way.
