Abstract— Monitoring the deformation of concrete dams is of vital importance for avoiding catastrophic loss of infrastructure and life. However, dams monitoring still being a challenging task. In the last years, significant efforts have been undertaken by international researchers to find an efficient way for deformation monitoring of this kind of structures. This paper aims threefold. Firstly, to present different methods and means using for monitoring concrete dams. Secondly, to identify the opportunities that could potentially improve the inspections and the monitoring behavior using Terrestrial Laser Scanner (TLS) techniques. Based on a dense and accurate 3D point cloud and images provided by TLS, it is possible to detect vertical and horizontal deformations and all pathologies affecting the dam safety, such as cracks. Thirdly, to show the importance of Geographic Information System (GIS) that allows managing a 3D database, spatial analysis of all external pathologies, planning with developing a suitable monitoring plan and decision making. In this paper, it is clearly highlighted the importance of using TLS and GIS in order to develop an effective dam monitoring process that can help identify structural problems before they become critical and endanger public safety.
