The modeling process of the relief occurs in a natural way as the result of the internal and external activities of the agents. Weather agents control the external actions of the natural origin. Although, the inadequated use of the soil by the disordely occupation and other degradation practices has provoked the acceleration of the erosive processes, started the alteration of the forms with the appearance of the ravines and gullies.According to Guerra et al (2004) the erosion of the soil occur because of natural causes: chemical and physical properties of the soils, kind of vegetable cover and human activities, whose the diversity and the magnitude change the equilibration of natural strength and accelerate the erosive processes.In Maranhão State, as well in São Luís, the disordely occupation of the space and physical factors like weather and soil favor the erosion in vulnerable areas. In this context, it is the área of Bombom Hill, where the irregular occupation process intentifies the transformation of the ground morphology and worsens the social enviromental problems.
