This study addresses the casual relationship between urban growth patterns and environmental phenomena, which we have in Geographic Information Systems (GIS) as a powerful tool to support urban planning and decision-making. In this sense, an analysis of susceptibility to flooding of regions through GIS represents important information for the public sector, as support to the urban zoning process, delimitation of risk areas and for the allocation of public resources, with corrective and preventive purposes. Thus, this study aimed to determine areas susceptible to flooding in in the municipality of Juazeiro do Norte, Ceará, through geoprocessing techniques. For that purpose, data on slope, elevation, accumulated water flow, curve number, soil type and land use and occupation were used. The results indicated that Juazeiro do Norte is a city of medium susceptibility to flooding, corresponding to 69% of the municipality and compromising 17% in a high susceptibility. The urban area of the Tiradentes neighborhood deserves alert due to its greater potential for flooding, where 79.5% of its area is very vulnerable. The generated map serves as an instrument for managing and monitoring extreme water events that happen routinely in the city. It also signals the community and managers to take measures to prevent and minimize flooding.

O projeto objetivou prover a diversos profissionais e estudantes, minicursos de introdução ao geoprocessamento utilizando o <em>software QGIS</em>. Executadas entre janeiro e dezembro de 2019, pelo grupo de extensão denominado Laboratório de Estatística, Modelagem e Geoprocessamento (LEMGE) da Universidade Federal do Cariri (UFCA), as referidas formações contemplaram 108 pessoas e visaram apresentá-las a uma ferramenta tecnológica gratuita, bastante utilizada na gestão de informações georreferenciadas. Concluiu-se que, na opinião dos participantes, as ações foram válidas podendo auxiliar tanto na sua prática cotidiana quanto na construção de novos conhecimentos, o que endossa a necessidade da constante aproximação de diversos nichos de trabalho ao estado da arte das geotecnologias contemporaneamente difundidas.
