Projeto de recuperação de área degradada no município de Medianeira-PR

Abstract

The intense exploitation brought great negative and impacting consequences to the environment. Agricultural areas and residential occupations in hazardous areas, among others, are factors that contribute to continuous and untiring environmental degradation. The worst stage of water erosion, that is, caused by rain, is the gull, responsible for great damage to the environment; Loss of soil mass and sedimentation of springs are some aspects the objective of the work was to elaborate projects for the recovery of degraded areas, aiming not only the recovery itself, but mainly the population's awareness of the issue of environmental preservation. The area of activity in Recanto Parque Iguaçu, located in the Sun and Gold line of the City of Medianeira. In the initial phase the identification and location of the erosion, already transformed into voçoroca was made, then the problem was analyzed and the mechanisms were pointed out that eventually contributed substantially to its evolution. Measurements were taken by fieldwork and every 7m stone barriers with a height of approximately 60 cm were installed in order to contain the water velocity thus containing soil erosion. After the barriers were established, a monitoring was carried out and observed that there was sediment accumulation inside the gull, which was previously dragged to the river. With the accomplishment of this study, it was possible to have a better knowledge about the soil conditions of the region, the climate and the importance of an environmental impact study to prevent this type of erosion.
