Abstract

This work aimed to elucidate the environmental degradation of the Mulato river basin, based on a series of factors resulting from the dynamics of the physical-natural
environment and/or actions generated by anthropic action. The study is based on the application of the methodology for Physical-Conservationist Diagnosis (DFC) supported by Geoprocessing. The methodology starts from the definition of six parameters to identify the risk of degradation, namely: Vegetation Cover Index (ICV), Current Cover (CA),
Declivity (DEC), Rain Erosivity (R), Soil Erodibility (K) and Drainage density (DD). The mapping showed that the portions of the BHRM that present areas with very low risk are concentrated in the southwestern portion and close to the river plains, while those that present a medium to very high risk of degradation occur in areas destined for agricultural practices. The efficiency of this methodology is highlighted, as the results are spatialized as real indicators of the state of degradation of this system.
