Abstract

Floods are phenomena resulting from the complex interactions of physical-natural components of the landscape. They are also among the most observed global natural hazards, with increased exposure due to population and economic growth in susceptible areas and global environmental changes (CECH, 2013; IPCC, 2012; MILLY et al., 2002). This project aims to identify and analyze, in an integrated manner, the natural systems present in the Atibaia River basin, which largely encompasses crystalline terrains of the western Serra da Mantiqueira, as well as lower areas of the Paraná sedimentary basin. The adopted methodology is based on the Russian-Soviet Geography approach, focusing on the development of landscape maps using geomorphological analysis as a criterion for the cartographic representation of the geosystems in the study area. This approach incorporates the concept of anthropic systems, expanding the discussion to the context of disasters. The geosystems will be mapped by integrating data on geology, relief, soils, vegetation, climate, hydrographic network, and morphometric information such as hypsometry and slope. The resulting landscape maps are valuable tools to support environmental planning and territorial management proposals, as understanding the dynamics and evolution of geosystems is crucial for guiding human actions in natural resource management, especially in risk management. Furthermore, this study enumerates the flood episodes that have affected each of the municipalities within the study area, categorizing them by date, impacted areas, and damage caused. Finally, the precipitation events responsible for triggering each flood episode will be characterized.
