The measurements, obtained through the use of the ADAS developed and installed by Prointega Ingeneria, are sent to the gestBarragens system, which is the LNEC and EDP data processing and management system used for monitoring, diagnosis and safety control of dams. 2. THE BAIXO SABOR DAM Baixo Sabor is a 123 m high concrete arch dam, 505 m long at the crest, designed, constructed and operated by EDP, located in the northeast of Portugal in Sabor river (a tributary of Douro river). The first filling of its reservoir, with a volume of about 1095 hm3, took place between December 2013 and April 2016. Fig. 1 Overall view of the Baixo Sabor dam 2.1. THE MONITORING SYSTEM OF THE BAIXO SABOR DAM In accordance with the best technical practices, the monitoring system of the Baixo Sabor dam aims at the evaluation of the loads, the characterisation of the rheological, thermal and hydraulic properties of the materials, and the evaluation of the dam structural response. The monitoring system of the Baixo Sabor dam consists of several devices which make it possible to measure quantities such as: concrete and air temperatures, reservoir water level, seepage and leakage, displacements in the dam and in its foundation, joint movements, strains and stresses in the concrete, and pressures, among others [1]. The system used for the measurement of the reservoir water level comprises a high precision pressure meter, which provides a record of the water 1089
