Cálculo do índice de qualidade de água em reservatórios tropicais com estudo de caso no Acarape do Meio

Abstract

The sustainability aspects in the use of the water resources have become, on the part of engineers, technicians and Governments, responsible for the Water Resources Management, an larger attention, in the search of better solutions for the problems that have been appearing as a consequence of the human most several needs. Those efforts have been finding in the Engineering Environmental support and great usefulness in the diagnoses of evaluation of the environment, seeking to allow rationality in their multiples uses. This work studied, through field research, associated with a methodology of calculation of the Water Quality Index, the environmental conditions of the Acarape do Meio Reservoir, in the State of Ceará, seeking to determine its water quality in a space distribution of the reservoir, showing, like this, the several critical points of it. The calculations of IQA-CETESB allowed concluding that the reservoir has, in their waters, a classification passing of Acceptable for Bad, second the CETESB classification, along its profile. Still regarding its longitudinal distribution, the results showed that IQA-CETESB oscillates between Acceptable and Bad, in agreement with the period analyzed. This result allows identifying the influence of the hydrologic processes in the quality of the water conditions of this reservoir.
