Morphometry and urban floods in the Jaguaribe River basin, Salvador-BA

Abstract

The aim of this research was to analyze the morphometric indices and their correlations with the episodes of floods in the Jaguaribe River basin. The landscape in the river basin is modified by the urbanization that resulted in the waterproofing of soils and the alteration of river channels. The use of geoprocessing techniques combined with the analysis of several technical works on the subject resulted in the Drainage Network Map. The studies in this map associated with the use of calculation methodologies indicated that morphometry would contribute to the rapid flow of water due to the elongated shape of the basin. However, with the intense anthropogenic changes, BHRJ currently has a strong propensity for urban floods.
