The urban area of Ponta Grossa city, located in Parana state, South of Brazil, has different kinds of erosion process, as landslides, river erosion, hillslopes, piping and gully erosion. These processes occur even in authorized as much as in unauthorized areas. The present research intends to comprehend the relations connecting the urban planning and the erosion process occurrences. As a base for the research, it was studied a gully erosion located near Jardim Santa Edwirges and Vila Romana. As well, the aims of this study it to comprehend which were the factors that influenced the occurrence and the evolution of this gully erosion. Therefore, the present research intends to investigate the relation between the rock base and its fragility to accelerated erosion, besides, it has been done an analysis of the rain data from 1946 to 2009, as the water is known as a relevant factor in the erosion process. Finally, it has been made chronological analysis, aiming to comprehend the influence of the street shapes, especially without a drainage system, as an influence in the development and evolution of the gully channels. Although, to elaborate the chronological analysis, it was used aerial photographs and a satellite image. The dates chosen were 1980, 1995 and 2009, because those were the available images with appropriated scale/resolution, according to the size of the studied area. It was also made a comparison of photographs and information acquired in loco, during the research time, as they made possible to observe the recent changes and the fast environmental degradation.
