FINAL REMARKS According to the recent trends in automatic monitoring dam systems having in mind the safety control in real time, the ADAS installed in the Baixo Sabor dam includes internal early warning control system allowing early identification and notification of potential situations to the entities responsible for dam safety. In this work, a methodology to the definition of triggers for the physical quantities observed in automated monitoring systems of the Baixo Sabor dam was presented. The definition of triggers for the uplift pressures measured on piezometers was performed through the use of HST models and measurement data. The proposed methodology are being used to the definition of the triggers for other physical quantities measured through the automated monitoring system. Although the importance of physical installation of the systems, it should be noted that the exploitation of ADAS total capacities also involves the incorporation of suitable software for the analysis and validation of the results obtained, based on representative models of the dam behaviour. So, it can be concluded that the automated monitoring system installed in the Baixo Sabor dam, with internal early warning control system, has a relevant contribution to assure an effective safety control of the dam.
