A construção do relevo antropogênico no aterro de resíduos sólidos de Manaus

Abstract

Population growth in cities has generated demand for essential services, such as access to health, housing and basic sanitation, such as solid waste collection services. In the city, not everyone is assisted with these services, which causes, in the case of urban waste production, dumping in inappropriate areas, giving rise to open dumps. This is the case of the Solid Waste Landfill of Manaus (ARSM), which started its activities as a dump. In the work carried out previously on this area, the landfill was not seen from the perspective of geomorphology, that is, as an anthropogenic relief, formed by technogenic deposits. Thus, this work had as general objective: to analyze the anthropogenic relief of the Solid Waste Landfill of Manaus (AM-010) formed by the tecnogenic deposits, having the following specific objectives: a) classify the anthropogenic relief formed by the tecnogenic deposits in the Solid Waste Landfill of Manaus; b) describe the construction of the implantation areas in the Solid Waste Landfill of Manaus; c) to map, through contour lines, the shape and altimetry of the anthropogenic relief of the Solid Waste Landfill of Manaus; d) make considerations about the type of use that will be given to the Manaus Solid Waste Landfill area after the end of its activities. Libault's (1971) methodological proposal used the four levels of geographic research: compilation level, correlative level, semantic level and normative level, together with Peloggia's (2017) classification of technogenic terrains. Thus, it was noted that the construction of the ARSM relief took place from the main massif, and from the implantation areas that stabilize this structure, in addition to the uses of areas that have essential services for the operation of the landfill. The altimetric values in the area can reach up to 143 meters in altitude, and the relief forms present in the perimeter present a hill pattern with a tabular top and terraces on the slopes, which is similar to the geomorphological structure in which it is implanted, in addition to having urbic layers. - cell. The relief present in the landfill is the result of the production and reproduction of the geographic space in the city of Manaus, which in turn generates forms that resemble the structure of natural relief, however with a highlighted altimetry, in this case, it makes up the local landscape.
