With the urbanization process, cities go through a disorderly growth, the population occupies areas in the relief considered inappropriate, without taking into account the natural dynamics that can compromise the undue occupation on sloped soils, the floods of river channels and water infiltration from rains on soils containing impermeable areas, it can cause serious damage to society. Erosions are often a consequence of the deficiency in urban rainwater drainage that does not support the amount of water coming from rain. The objective of this research, thinking about the process of occupation of the landforms and consequent waterproofing of the soil surface, the objective of this study is to understand the erosion processes installed in some neighborhoods in the urban area of Ituiutaba - MG, emphasizing the processes that suffered acceleration due to to anthropic interference generating erosive features that cause disturbances for the residents, as well as loss of pedogenetic material. In order to carry out this monograph, bibliographical reviews, site searches, fieldwork in the study area were carried out, following a description sheet of the landscape and erosions studied as a guide for various information needed for the work. As a result of the research, it was found that problems arise related to the rainwater drainage system, the paving of the relief causes the impermeabilization of the soil, which reduces the amount of water infiltrated into the soil, the amount of storm sewers (wolf mouths) if insufficient as the streets and avenues have a steep slope, a fact that accelerates the flow of water and directs it more strongly to the valley floor, where erosion is found in the following neighborhoods of the city of Ituiutaba, Nova Ituiutaba, Cidade Jardim and Novo Tempo II, caused by the lack of urban planning, disrespecting the residents of these neighborhoods.
