Suscetibilidade da Bacia do Rio Bengalas a deslizamentos de terra
Landslides have frequently occurred in last years, due to the disorderly
grownth of the cities and the occupation of risk areas by the poor population, causing social,
environmental and economic impacts. Urban areas in expansion move to geologically
unstable areas and topographically inclined, such as the Basin of River Bengalas, located in
the city of Nova Friburgo, mountainous region of the State of Rio de Janeiro, Brazil. This
article aims to present the model survey to assess the susceptibility of the Basin of River
Bengalas to landslides, which in january 2011, with the occurrence of heavy rains, caused
landslides that impacted in the death of 429 people in city of Nova Friburgo. For the case
study, several investigations have been made related to the areas of the basin, such as slope,
soil conditions, lithology, land use and cover, vertical and horizontal curvatures. With this
study it was possible to understand how the natural and anthropics elements of the basin are
related to the local dynamics of the disasters regarding to their interferences in the induction
of landslides, thus enabling improved public management of the Municipality regarding the
use and division of land, from the identification of areas Basin of River Bengalas susceptible
to landslides
