ANÁLISE HIPSOMÉTRICA E MORFOESTRUTURAL DO DOMÍNIO VAZA-BARRIS, SERGIPE

Studies of morphometric and morphostructural parameters are essential for understanding the geomorphological landscape. Quantitatively evaluate the physiographic dynamics and the performance of the drainage network in the modeled. The Vaza-Barris Domain is a geotectonic unit inserted in the Sergipana Folding Range and covers the states of Sergipe and Bahia (Brazil). Four hydrographic basins are included in the unit: Rio Sergipe, Vaza-Barris River, Piauí River and Rio Real. This research analyzes the morphometric indices of hypnometry and morphostructure applied in the areas of the four hydrographic basins, quantitatively evaluating the drainage behavior in the evolutionary process of the morphological landscape and the lithological/structural control in the spatial definition and arrangement of drainage. The methodology consisted of compiling existing data and acquisition of new data through the processing of satellite images and Model Digital Elevation, in the treatment and interpretation for the elucidation of the facts. Digital Elevation, in the treatment and interpretation for the elucidation of the facts. It is concluded that the structural, lithological, tectonic and physiographic singularities interfered in the performance of the drainage network on the carving of the relief of the Vaza-Barris Domain.
