Abstract

This paper aims to present an analysis of Tamanduazinho River, which is located in the Parana state. The Tamanduzinho River source is in Santa Terezinha de Itaipu city and it flows into the city of Foz do Iguaçu in Iguaçu River, its watershed contains an area of approximately 145,340,900 m² where the bedside drainage of Tamanduazinho River lies degraded by mining clay and inadequate land use. To identify the problems of the area, it was divided into ten different units to better identify critical points through the utilization of a methodology based on an analysis of the impacts and the creation of geographic areas called landscape units. The main impacts found were lack of riparian vegetation around the source, habitat destruction, water pollution, erosion and formation of gullies resources. Taking into consideration the importance of restoring and preserving this environment, this study proposes a recovery for each area defined by the decomposition of the geographic space of landscape units; this decomposition represents the environmental risk of soil associated with its current use. The analysis of the environmental impacts found in the ten units demarcated landscape allowed proposing measures for the rehabilitation of the area as a whole, involving mainly the gully control, reforestation and soil conservation management. Similar features to the landscape units such as lack of vegetation and erosion and gully formation, in this way for some landscape units, the proposed recovery was the same found already in the area. The recovery of this bedside drainage will contribute towards maintaining environmental quality.
