Utilização da biomanta de fibra de coco como técnica de bioengenharia para o controle de erosão em taludes

Abstract

Landslides in Brazil constitute a serious problem that affects various regions of the country, especially during periods of heavy rainfall. These natural events have caused numerous tragedies over the years, resulting in significant human and material losses. In order to prevent these situations, geotechnical engineering has been seeking traditional solutions to stabilize slopes. However, many of these solutions come with high costs and may face challenges due to the terrain's topography, which sometimes makes equipment usage difficult. On the other hand, soil bioengineering emerges as an alternative, focusing on the combination of biologically active elements with inert ones. In this context, this work aims to describe the artisanal process of manufacturing a 1.50x2.00 meter biomat made from coconut fibers, with the purpose of evaluating its performance when applied to a natural slope. To do this, 35 discarded coconuts were collected from a kiosk in the João Pessoa region, which served as the primary source for making the biomat. Thus, after a performance analysis of the biomat over 5 weeks, we can conclude that this solution proves to be viable as it does not harm the ecosystem, reuses discarded materials, stimulates local income sources, and has a lower production cost than the purchase value of conventional screens.
