Considerations regarding hydro power station monitoring objectives through geodetic measurements.

This paper seeks the stability of concrete or rockfill dams located on Someșul Cald riverthrough geodetic and topographic measurements. Tracking the dam stability is achieved in terms ofplanimetry and altimetry. . For the planimetry tracking can be used micro-triangulation method,trilateration method or combined methods. In terms of altimetry can be used the geometric geodeticleveling method. For the case study was chosen TarniA£a dam which was monitored in terms ofplanimetry and altimetry. In determining the azimuth and zenith observations we used a precision totalstation (2cc), and to make the altimetry observations we used a high precision digital level andmeasuring staff with bar code. Processing of geodetic observations was achieved by conditionalmeasurement method.
