- Abstract
The present work aims to elaborate a proposal of framing the water bodies in classes of usage in the Santo Antônio river basin, located in the state of Minas Gerais. Classification varies according to water quality in five classes (special, 1, 2, 3 and 4). The criteria used to elaborate the proposal were the usage and occupation of the soil, purposes of the grants, volumes granted, minimum reference flow and population density. For each criterion a weight was attributed, and the framing map was generated from the overlay of the adopted criteria maps. Due to limitations in the databases, it was decided to put foward the framework for the main rivers of the basin. Framing Conformity Index (FCI) was also calculated in order to define priority areas for intervention purposes. As a result, Guanhães and Preto do Itambé rivers were classified in classes 1 and 2. The Peixe river was classified as class 1 and the Santo Antônio and Tanque rivers were classified as class 2. The section classified in class 1 of the Guanhães river was the one that presented lower FCI, therefore intervention measures are necessary.
