Mapeamento De Áreas Suscetíveis À Ocorrência De Deslizamentos Na Microbacia Do Ribeirão Baú, Ilhota/Sc, Com O Uso De Modelagem Matemática

Abstract: Deslizamentos ocorrem no Brasil em encostas íngremes após eventos de chuva. No ano de 2008 ocorreram precipitações intensas e concentradas que provocaram inúmeros movimentos de massa no estado de Santa Catarina, principalmente na área do entorno do Morro Baú, mudando significativamente a morfologia dos vales e encostas e atingindo a população local. Neste sentido, este trabalho tem como objetivo elaborar o mapeamento de áreas suscetíveis à ocorrência de deslizamentos, a partir do modelo SHALSTAB aferindo-se o… Show more

“…In this study, the ASA tool (Automatic SHALSTAB Analysis) was used, developed by Sbroglia et al (2017), which is added to the Toolbox of the ArcGIS geoprocessing software, containing the automated routine of the SHALSTAB mathematical equation (equation 1). This tool automates the modeling processes (speeding up the results) and allows spatial variation of soil parameters, which, for the Rio Garcia basin was based on the geotechnical units polygons.…”

“…2021 Landsliding Stability Model) has been used frequently in several regions of Brazil and at different scales for mapping susceptibility to translational landslides. For example, in hydrographic basins located in the Maciço da Tijuca in Rio de Janeiro at the 1: 10.000 and 1: 50.000 scales (GUIMARÃES, 2000;GOMES, 2006), in Minas Gerais at the 1: 50,000 scale (RAMOS et al, 2002) and in Santa Catarina on a scale of 1: 50,000 (REGINATTO, 2013;SBROGLIA, 2015). SHALSTAB incorporates topographic parameters (slope, contribution area and contour length) and soil parameters (effective friction angle, effective cohesion intercept, specific weight and soil thickness) in its analyses.…”
