Análise espacial da modificação do relevo no centro da cidade de Manaus — AM

Abstract

The dissertation investigated the transformations of the relief in the central urban area of Manaus, highlighting the modifications resulting from human occupation from the pre-colonial period to the present day. The main objective is to analyze how the relief has changed over time due to urban growth and structural interventions. The adopted methodology follows Libault’s proposal (1971), which structures the research into four levels: compilatory, correlative, semantic, and normative. These levels range from data collection in texts, documents, and maps to the analysis and graphic representation through thematic maps, charts, and photographs, facilitating the interpretation of relief modifications. The results show that Manaus initially maintained a balanced relationship with the natural environment. The arrival of Portuguese settlers brought the first interventions, such as the construction of the port and the Fortaleza de São José do Rio Negro. However, the Rubber Boom marked a drastic change with the Europeanization of the city and major infrastructure works, such as the canalization of streams and the creation of reclaimed areas. These changes altered the original morphology, eliminating natural barriers and exposing the city to new structural risks. Many underground galleries, now deteriorated, pose an imminent risk to urban safety and historical heritage. The research contributes to urban and geographic studies by integrating historical and geomorphological aspects, highlighting the importance of sustainable urban planning. The warning about the current state of the galleries and the lack of systematic records emphasizes the urgency of further investigations and preventive policies. Thus, the work not only expands knowledge on the evolution of Manaus' urban relief but also proposes a reflection on more sustainable and environmentally integrated urban practices.
