Abstract

The paper presents a set of erosion and mass movements susceptibility assessment procedures applied to the area of direct influence of the Quebra-Queixo hydroelectric power plant, located on the Chapecó river, Santa Catarina state, Brazil. The susceptibility assessment was based on the use of multi-criteria decision supported by a GIS. For the composition of the multi-criteria decision relief, soil and vegetation cover criteria were used, and were divided into eleven predominant factors. The weighted linear combination method was used in the association of factors, with weights and scores attributed to the method through technical consensus. The main result was a thematic map containing the spatial distribution of the erosive and mass movements susceptibility classes for the hydroelectric power plant's surroundings.
