Técnicas de Bioengenharia e possíveis soluções para estabilização de taludes de corpos d’água em São Gabriel – RS

Abstract

This research was developed as a literature review with central theme focused on bioengineering solutions, characterized as stabilizing structures of hillsides against erosion and landslides in areas of rivers and urban streams, also bringing as focus analytical observations for future application of the same techniques in the recovery of three stretches of the Rio Vacacaí inserted in the urban area of the municipality of São Gabriel, called the flow paths as Sanga da Bica, Sanga da Riveira and main Vacacaí, in the region of Campanha do Estado do Rio Grande do Sul. It was briefly described the characteristics of riparian forests and their ecological importance in the maintenance of the river ecosystem, the distribution of water bodies in the Brazilian territory, the current legislation of Permanent Preservation Areas in urban areas and their actions, methods of passive and active management of water bodies and their importance in the physical characterization of water courses, as well as the broad classification of biotechnical works for stabilization, prevention and correction of river slopes.
