Flood dynamics: A geoecological approach using historical cartography and giscience in the city of petrópolis (Βrazil)
MetadataShow full item record
AbstractDynamics, structure and function are geoecological characteristics that define landscapes. These characteristics help explain landscape processes, such as floods. This article analyses geoecological variables to understand flood dynamics in the original historical district of Petrópolis City (Brazil). Concepts and techniques of historical cartography and GIScience were used to analyse geoecological variables in three river basins (Quitandinha, Palatino and Piabanha) within the study area. Each basin had a river island which was excavated and removed. The Quitandinha River Basin had the largest river island (965 m2), the highest Edification Index (44.12%) and the most favourable geomorphological indices for the occurrence of floods. Hence, the basin recorded 93% of flood events within the three basins. Multiple geoecological variables influence flood dynamics. In this urban landscape, changes in the drainage network, intensified by disorderly urbanization and geomorphological processes, are extremely important in understanding flooding processes.
