Study of the feasibility of intervention to mitigate erosion in the forest fragment of igarapé da vovó in Manaus-AM

Abstract

The Amazon region can be seen as an immensity of natural resources of all types. However, its diverse ecosystems are fragile, especially its different soil types. Because of the constant and accelerated urbanization of its spaces, several negative externalities occur, such as the silting of miniature river courses, known as streams. In this sense, this study aimed to present a proposal to treat and act to contain the degradation of Igarapé da Vovó and recover the areas surrounding it. To this end, it proposes a corrective intervention using low-impact technology (LID) due to the absence of a water energy dissipation device in the drain outlets. The proposal aims to obtain the results that the area adapts to the techniques used significantly, reducing runoff, eliminating erosion, increasing the volume of the basin, and reducing silting. The purpose is that this action can ensure that the spring increases its water capacity, becoming a successful reference for sustainable intervention in solving siltation and slope erosion in a fragment of Amazonian urban forest.
