This article aims to analyze and characterize the problem of anthropic interventions along the Tucunduba stream, located in the city of Belém-PA, aiming to show how the process of urban expansion interferes with the water body, as well as the consequence of the disordered occupation in the margins of the igarapé. Since it causes soil changes and increased runoff, which is responsible for transporting organic and inorganic materials to the river, it significantly increases its pollutant load, causing flooding, river eutrophication, and other problems of water degradation. The bibliographic review and the on-site visit, as well as photographic record and georeferenced images made available in Google Earth, were used for the basement of the same, observing the general condition of the area, to characterize the anthropic factors that contribute to the degradation of the Igarapé.
