Os processos erosivos na estrada de Vila Amazônia, Parintins – AM

Abstract

Due to the fact that almost all the extension of Vila Amazônia road is not paved, it becomes more vulnerable to erosive processes. Erosion is a natural process that occurs in all types of soils, and depending on the environment it can occur slowly or abruptly by changing the relief. Thus, this article aims to identify erosion processes such as sucos, ravines and gullies in the initial stretch of Vila Amazonia road and in its surroundings, trying to identify the major problems caused by these incisions to the environment and the residents locations. It is also important to describe the main vulnerability factors involved in these erosion processes, especially the gully because it is a natural process incision with a greater impact on the local environment. The place chosen for the study area was the rural area of ​​Vila Amazônia, located on the right bank of the Amazon River at a distance of approximately 6 (six) kilometers from the city of Parintins-Am. More precisely, on the road linking the community of Santa Maria to the community of Santa Rita da Valéria, this route is delimited from the beginning of the same, passing through the community of Açaí, prolonging by the vicinal that leads the community of São Jorge do Jauari. This work was accomplished through field research and on-site observations, measurements with trenas, image registration and mapping with GPS support. In relation to erosive processes, juices, ravines and gullies can be found on the road, which through literary readings can understand the factors that can cause these incisions and their consequences to the environment. With the measurements of the gullies, it was possible to observe the amount of soil eroded, as well as the consequent silting of the streams near it and the risks they cause to the residents living in areas close to these incisions. Faced with such facts, this research seeks to verify the damages that the erosive processes cause to the environment and what environmental and social problems these incisions cause to occur around the road of the Vila Amazônia community.
