Dinâmica dos Movimentos de Massa em bacias hidrográficas urbanas

Abstract

Landslides are natural processes that promote changes on slopes. As a result, this work aimed to identify and assess the spatial distribution of areas prone to Shallow Translational Landslides in the Fradinhos drainage basin, located in the municipality of Vitória, ES, taking into account the intense rainfall event of 2013. The Fradinhos river drainage basin is located in Vitória Metropolitan Region (RMGV) and presents occurrences of Mass Movements, a fact that corroborated to develop this work. For the data modelling, the Transient Rainfall Infiltration and Grid-Based Regional SlopeStability Model (TRIGRS) was used, along with an elevation model with a spatial resolution of five meters and data from five field collection points. This study aimed to understand the spatiality of mass movement processes and the role of rainfall in the dynamics of the basin's topography, while also contributing to territorial management.
