We present and discuss first results in Spain achieved on the application of Sentinel-1 mission for the monitoring and survey of relatively small and isolated hydrological critical infrastructures like a dam and its surroundings. We describe the results obtained for the Siles dam, located in the province of Jaén (Spain), during its settlement and initial load process. ESA´s Sentinel-1A Interferometric Wide Swath (IW) SAR data are used and processed using the Coherent Pixel Technique (CPT) algorithm. A comparison of the A-DInSAR results with in-situ measurements will be also given. First results for this comparison shows a good agreement between A-DInSAR and levelling for the maximum value of subsidence. The results show that Sentinels program can be a very good choice for this type of studies due its short repeat cycle and spatial resolution as well as the open data Access policy which permits to obtain a high number of images without charge. The last facilitates to define a sustainable operational monitoring system.
