Brasil e suas águas – estudo das toponímias nas redes hidrográficas
Abstract
Brazil has one of the largest water sources in the world, which embraces a great complexity in its hydrographic networks. In this work, we seek to highlight the variety of toponymy of Brazilian watercourses, distributed throughout the national territory, which demarcate regional issues and the historical evolution of human occupation. Within this context, the objective of this work is to identify, present, categorize and rank the different Brazilian toponymy, creating a base document of these denominations. The methodological procedures consist in acquiring the cartographic bases of the drainage network, on a 1: 100,000 scale, which were spatialized, according to their location and the number of watercourses with the same name, allowing the creation of five different toponymy scales (National, Regional, Local, Microlocal and Border). In order to achieve this objective, is was used both length and hierarchical order data. As the final result, it was possible to rank the country's toponymy in five orders of magnitude, in association with its regional historical-cultural specificities, for technical-scientific purposes. Thus, the fifth order involves the national scale, with the Rio toponymy being the predominant one. The fourth order consists of toponymy on the regional scale, such as Ribeirões, Corixos and Riachos. The third order also has the toponymy of the watercourses on the regional scale, such as Arroio, Lajeado, Córrego, Igarapé, Vazante, Paranás and Riozinhos. The second order refers to the other watercourses of the local scale, as well as the first order, which includes the microlocal scale watercourses and in the border area of Brazilian international limits, such as Arroyo, Caño and River.
