Desenvolvimento de uma lógica fuzzy para avaliar o índice de estado trófico modificado do reservatório Acarape do Meio

Abstract

In an attempt to reduce water scarcity is common in regions with semiarid features the construction of large reservoirs. On the other hand, water storage in reservoirs makes these waters vulnerable to a greater risk of degradation. Thus, with increasing demands for water use, quality indicators have shown a considerable degradation in water bodies. This methodology allows us to make a diagnosis of the current state of the reservoir Acarape do Meio. For this, it was used the calculation of modified trophic state index (TSIM) to assess the environmental conditions of the reservoir Acarape do Meio in the state of Ceará, in order to identify the major transformations in their trophic levels, as well as identify the main causes of a possible eutrophication process in this water body. It was used field data of the years 2001 and 2002.
