Resumo (PT): The present work establishes a step-by-step methodology aiming the development of a practical tool in the design of closure and contingency plans of tailings dams. Risk assessment and the foreseeable scenarios in case of a break, based on mathematical models, are mandatory in these plans. Different scenarios of rupture of the dam are established, based on geostatistical methodologies, allowed to build flood maps. These maps allow not only an a priori evaluation of the areas eventually affected and the impact on neighboring populations, but also constitute key elements in the implementation of emergency procedures that must accompany the life of the structure. The developed methodology was applied in Portuguese new project as a case study, revealing a good acceptation by the mine project sponsors as well by the authorities.
