Dam removal is becoming a current practice worldwide. Several causes can justify the removal of a dam: security issues, siltation due to age, fail to fulfill project purposes, etc. In Brazil, the development of scientific research in this theme is scarce and does not exist in the Northeast, where construction of dams is strongly linked to regional culture. However, this research is necessary, considering that some dams are quite old. In this context, a multicriteria model was constructed to evaluate the vulnerability of dams. It allowed to define the IREB, an index that establishes three possible recommendations for action: dam removal, recovery or keep it as it is. The model was constructed following the MACBETH methodology and using the M-MACBETH decision support system in interaction with various experts. To test the model, information regarding three dams was used: Ubaldinho, Acarape do Meio and Jaburú I, located in the State of Ceará. The results were consistent with those expected and the analyzes performed demonstrated the requisiteness of the model.
