Every man-made structure creates certain risks -dams are no exception. Most failures in man-made structures that have occurred could have been avoided if the structures' behaviour had been inspected, monitored, and analyzed continuously, and if proper corrective measures had been taken in a timely fashion. The DSI (The General Directorate of State Hydraulic Works), which is the institution responsible for dam safety, has long used surveying methods to measure the displacements of geodetic points as a part of dam monitoring policy. In this study, we focus on the dam's mechanical behaviour throughout a time period of more than 10 years. These study results have been derived from a separate, ongoing project that has monitored deformation on the Ataturk Dam and is now determining the water level of the reservoir. The project results show that although the dam body has become more stable and the water load behind the dam has increased, the rate of displacement of the dam has declined significantly. From these results, it can be seen that the reservoir water level can be increased evenly over time and that 542 m is the maximum water level of the dam's reservoir.

“…Accuracy, cost, and automation are the important factors that need to be considered in dam deformation monitoring. The traditional monitoring methods, such as total station, level, and theodolite, did not allow the real-time, continuous and automatic monitoring of dam [3]; GNSS (Global Navigation Satellite System) has been used for the surface deformation monitoring of the engineering structure based on its highprecision and high-automation characteristics [4][5][6] but with higher cost of geodetic receivers severely limiting its application in the dam deformation monitoring.…”

“…Meanwhile, not like the traditional GNSS multiantenna technology, the dual-channel RF front-end and digital correlator share the same clock module, avoiding cycle slip error and realizing singleepoch positioning, owing to electronic component reduction of clock-synchronized dual-antenna receivers, the newgeneration N71JN from Shanghai Huace Navigation Technology Ltd. in Figure 1, which has low cost (<$1565) and light (<3.6 kg). Moreover, most of the dam GNSS surface monitoring schemes are unreasonable, and GNSS monitoring station overabundance results in tremendous waste of equipment resources [4,6,10,12,14].…”

Higher monitoring cost is the main limiting factor in the application of geodetic receivers in dam deformation monitoring, as the number of receivers applied in one dam is always too large. In this paper, an improved GNSS monitoring scheme is proposed. Firstly, three-dimensional finite element model is built to simulate the main deformation part of the dam, and only one clocksynchronized dual-antenna receiver is used to set the reference and monitoring stations; then, the dam displacement warning standard is determined based on the relationship between the corresponding surface displacement and safety factor of the different mechanical parameter combination; finally, through BDS/GPS dam deformation monitoring system for Lijiaxia in China, the operating status of dam is evaluated. Through comparative analysis, it is found that the scheme is feasible.

“…Until recently, many studies were conducted concerning monitoring structural responses of dams, specifically, earth dams (Guler et al 2006;Bayrak 2008;Gikas & Sakellariou 2008a;Ehiorobo & Ehigiator 2011;Kalkan 2014) and concrete dams (Pytharouli & Stiros 2005;Sortis & Paoliani 2007) on the bases of geodetic and geotechnical methods. Guler et al (2006) evaluated the surface movements of Alibey Earth Dam (Istanbul) by means of geodetic and geotechnical methods.…”

“…The results showed that overall movement of the embankment occurred in the SW direction due to the hydrostatic pressure from the dam reservoir. Kalkan (2014) determined the magnitude and direction of radial deformations of the Ataturk Dam, the largest dam in Turkey. Additionally, though not significant, the correlation between the radial movements in embankments areas and the reservoir water level was investigated.…”

The present study evaluates the dynamic behaviour of the Ermenek Dam, the second highest dam in Turkey, based on conventional geodetic measurements and Finite Element Model (FEM) analyses during its first filling period. In total, eight periods of measured deformation are considered from the end of construction until the reservoir reached its full capacity. The displacement response of the dam to the reservoir level and to seasonal temperature variations is examined in detail. Time series of apparent total displacements at the middle of the crest of the dam exhibits periodicity and linear trends. Correlation analysis revealed that periodic and linear displacement responses of the dam are related to variations of seasonal temperature and linearly increased reservoir level, respectively, indicating a relation between temperature, water load and dam deformation. It is also concluded that measured deformations based on geodetic data show good agreement with the predicted deformation obtained by the FEM analysis.
