Evaluation of the Movements of the Dam Embankments by Means of Geodetic and Geotechnical Methods

Displacement response of a concrete arch dam to seasonal temperature fluctuations and reservoir level rise during the first filling period: evidence from geodetic data

“…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.…”

Settlement analysis of the Mornos earth dam (Greece): Evidence from numerical modeling and geodetic monitoring

“…Comparative results that cover long periods of the lifetime of a dam are rare in the literature (e.g. [12]) due to unreliable or incomplete data records.…”

From Theory to Field Evidence: Observations on the Evolution of the Settlements of an Earthfill Dam, over Long Time Scales

“…This makes the probability of a dam failure significantly higher during the first years of its operation [16]. The failure risk is estimated to be substantially decreased in the long-term for mature earthfill dam structures [9]; however, this does not take into account dams subjected to extreme flooding, for example, in an annual or biannual cycle, which is a situation that has become more and more frequent lately [4].The deformation rates of earthfill and rockfill dams are affected by many factors, including internal erosion, slope stability, secondary consolidation of the core, the creep of shoulder fill, and stress changes due to varying reservoir water levels and seismic activity [17].The relationship between the reservoir level fluctuations and the deformation patterns of earthfill dams has been the focus of a number of studies, e.g., [17][18][19][20]. A decrease of the reservoir level is followed by a decrease of vertical stresses and higher settlement rates, and as a result, a rapid drawdown could potentially result in slope instabilities due to the heave of the upstream slope.…”
