ABSTRACT: The city of Brasilia, Brazil, is internationally known for its modern architecture based on the urbanism project of Lúcio Costa, which contemplated the urban center. Nowadays, despite partial planning and being one of the most famous urban landscapes in the world, the city presents frequent and challenging problems, among which we can highlight the countless cases of floods in various sectors of the urban area. This research had the objective to analyze the processes of use and occupation of the land in two drainage basins of first-order located in different urban nuclei full of paradoxes. Two drainage basins were selected, one located in Asa Norte, that is, inserted in the original planning of Lucio Costa, and another located in a region of recent urban expansion called águas Claras. For both basins, the analysis of land use was carried out in two distinct periods, 1964 and 2019. The results indicate that the city advanced exponentially over the original vegetation areas, with changes above 500% of the replacement of savannah by urban area. It should also be noted that the mere architectural planning of the city did not take into account the essential characteristics of the territory, since basic elements, such as topography and relief, that provide extremely relevant subsidies for drainage systems, were relegated.
