Análise ex post do estudo de impacto ambiental: O caso do Açude Atalho em Brejo Santo, Ceará

Abstract

This work aims to analyze the Ex Post of the Environmental Impact Assessment (EIA) and the water quality of the Atalho dam, located in the municipality of Brejo Santo, Ceará, Brazil. This study wants to identify the environmental feasibility of the Atalho Public Dam Project through the analysis of the main environmental impacts resulting from its implementation and operation. The impact evaluation used was led based on a considering evaluation method developed by Bianchi, Nascimento and Gurgel Júnior, a variation of the matrix method developed by Leopold. The whole analysis of the dam, represented by joining the results from the physical and functional areas, demonstrated that, in its original version, the project presents a sum of benefits considered inferior than the group of adversities and not defined impacts, what characterizes it as undefined or badly planned. The incorporation of environmental protection measures, however, could be able to revert this scenario by leading the dam project as favorable for the natural environment.
