CARACTERIZAÇÃO AMBIENTAL E ANÁLISE MORFOMÉTRICA DE BACIAS HIDROGRÁFICAS URBANAS: O caso do município de Bom Sucesso - MG

Abstract

Water occupies a prominent place among natural resources, being one of the most abundant substances on the planet and indispensable to our life. With the growth of several of the Brazilian cities that occurred recently, urban environmental imbalances have intensified in the same order, forcing municipal governments to adopt changes in environmental governance. Thus, municipal master plans are being developed with actions to protect water resources against the growth of communities, however, many are not concerned with the continuous monitoring of the environmental health of urban ecosystems, especially urban springs. One of the ways to diagnose the environmental quality of urban springs is to identify the environmental impact index in springs (EIIS). In this work, the EIIS was associated with the analysis of morphometric characteristics of two urban hydrographic basins representative of Bom Sucesso-MG, a municipality located in the Midwest of Minas Gerais. In addition to the EIIS, the compactness coefficient (Kc), form factor (F) and circularity index (Ic) were identified. The applied methodology proved to be adequate, establishing a technical and efficient approach in obtaining consistent data to subsidize environmental governance, which can be applied in the other urban basins of the municipality, helping to establish a public policy. Many problems observed in urban basins can be mitigated with simple measures implemented by the municipal government or the community, improving the environmental classification of these environments.
