Análise dos impactos ambientais na microbacia da grota do Coringão, Marabá/PA

Abstract

This study aimed to point out the problem of environmental impacts caused by the urbanization process. Which caused the occupation around the main channel of the Grota do Coringão micro basin. The Grota urbanization process, with various types of use and occupation for years, has been generating some environmental impacts in the area causing the degradation of permanent preservation area. The anthropic action was responsible for processes such as; soil erosion, compaction, sealing, flooding and removal of riparian forests from the Grota do Coringão micro watershed área. In addition to the problems related to environmental quality, these impacts also directly affect the lives of families residing on the site, as they experience periods of flooding, lack of sanitation and adequate infrastructure. Based on this problem, the importance of watersheds and the impact of environmental impacts on the grotto were addressed. Through geospatial analysis we can identify and express and spatialize these phenomena through thematic charts that were elaborated and analyzed. These are the map of slope, geological chart, permanent preservation area, flood and last of the sanitary sewage area of the Coringão Grota.
