Análise dos impactos ambientais decorrentes do processo intensivo de uso e ocupação do solo ocorrido na microbacia do Córrego do Barbado, Cuiabá-MT

Abstract

Many brazilian states and municipalities find difficult to effectively manage urban water resources that are their responsibility. This situation leads to a reflection on what could be done to alleviate these dilemmas. For that the present study was aimed at making the environmental diagnosis of Barbado Stream Watershed (BSW), with the aim of detecting the main environmental problems caused by urbanization, in order to find out preventive and corrective measures in line with current legislation. Thus, it was necessary to implement some studies in the BSW as: (1) to carry out physical characterization; (2) to check what are the environmental impacts occurred in the basin; (3) to evaluate the sanitary conditions in the watershed; (4) to assess whether the changes occurring are reversible, and (5) to compare the actual situation with the current legislation. The results were that the BSW is in advanced stage of urbanization whit a percentage of 92.4% and 7.6% of urban vegetation, respectively, covering a total area of 13.8 km2. These values show that urbanization process is taking place, and it is not considering hydrographic basin as an urban planning unit, having its natural landscape been totally altered in whole basin, keeping only the main spring partially in agreement with the actual legislation.
