To understand the geomorphological implications coming from anthropogenic activities in the study area in this time, the principles of Systems General Theory which allowed the comprehension of area as controlled system due to anthropic interference. The confection of geomorphological map, land cover map and declivity map as well as fieldwork allowed to collect data whose analyses made it possible to identify the geomorphological features brought by the urban growth. Therefore, the main changes observed refer to alteration in the feature of waterway due to process of channeling, decrease natural topographic breaks and advent erosive features.
