Considerations Regarding Hydro Power Station Monitoring Objectives Through Geodetic Measurements

Abstract. This paper seeks the stability of concrete or rockfill dams located on Someşul Cald river through geodetic and topographic measurements. Tracking the dam stability is achieved in terms of planimetry 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 geodetic leveling method. For the case study was chosen Tarniţa dam which was monitored in terms of planimetry and altimetry. In determining the azimuth and zenith observations we used a precision total station (2cc), and to make the altimetry observations we used a high precision digital level and measuring staff with bar code. Processing of geodetic observations was achieved by conditional measurement method
