Monitoring and diagnostics of hydrotechnical objects provide knowledge about technical condition of the object. The main purpose of the evaluation process is to determine the technical condition at a certain time of use, by defining its stability and security. Technical diagnosis , defined as a set of methods and means to assess the causes, evolution and consequences of given set of technical facility, is a technical system. In the case of dams, monitoring and diagnostics based on active systems, deliberately designed , generating and processing information that are the basis for the assessment of their technical condition . In this article we present the opportunity to enrich the technical monitoring system of water dams by the technology of terrestrial laser scanning (TLS) . Terrestrial laser scanning is a device metrology , which in a non-contact measures the object and saves it in the form of an oriented point cloud . The analysis of the technical system, supported by TLS technology was conducted with regard to water dam in Rożnów. ...
