Abstract

Debris flows are one of the most destructive types of mass movement due to its capability to transport and entrainment of different materials through long distances. Despite the high number of catastrophic occurrences related to the process, researches about debris flows are still limited when compared with another process, such as landslides. Similarly, it is needing the deepening of studies about debris flows and evaluation analysis, aiming to avoid new casualties. Thereby, the main goal of this project for this internship the evaluation of debris flow's analyses methodologies used in Vancouver, Canada, and its applicability in Serra do Mar Mountain Range, in Brazil, in order to favor a better understanding of the process. To achieve this goal, were established the following steps: (a) field works to areas with occurrence of debris flow; (b) evaluation of methodologies of study and the viability of its application in Brazil; and (c) mapping of debris-flow characteristics. As a major contribution of this research, there is an increase in the knowledge about debris flows and the possibility to use new methodologies to evaluate debris-flow occurrence in Brazil. (AU)
