AbstractIn the safety assessment of hydro-technical objects, it is necessary to combine different measurement techniques, calculations and experience of specialists in various fields of engineering. That is possible due to the current development of surveying technology. Undoubtedly, the integration of measurements, including technical assessment as well as object behaviour modelling, makes it possible to perform more comprehensive assessment of objects. Nevertheless, in order to obtain a multidimensional overview of an examined object – especially water dam – it is necessary to know all the possible errors that appear along the “observer-instrument-object” path. In this paper, the authors intended to investigate the influence of atmospheric conditions on the results of geodetic deformation measurements and attempted to consider surface deformation analysis, which is part of obligatory inspections of hydro-technical objects. The study was based on the geometry assessment of the vent wall of Rożnów water dam located within the borders of the South-Polish Protected Landscape Area. The measurements took place in the years 2013‒2015 and were performed using Z + F Imager 5010 laser scanner equipped with an integrated thermal camera. Surveying results and analyses based on archival data and forecasts of atmospheric conditions at the location of the hydro-technical facility can be applied while elaborating the rules for a control date selection. The proper definition of a measurement cycle will make it possible to avoid errors of interpretation for those facilities important from the flood protection, recreation and nature perspectives.
