Floods are natural processes capable of destroying cities and lives, causing immeasurable impacts on humanity. The increase in the occurrence of such tragedies is remarkable. Factors interfering with it may be population growth and a fast urbanization. The city of Sorocaba, in São Paulo state, Brazil, is an example of this problem. This study aimed to evaluate the degree of flood risk in urban areas, suggesting an alternative evaluation and a prevention method to decision-making on territorial planning. Therefore, fuzzy logic combined to geotechnology was used for the analysis and identification of areas with a higher degree of relevance to flooding. The evaluated areas have a high risk of flooding during January, but care should be improved for the period between November and March.
