Study of the long term behaviour of Krestena Dam based on the analysis of geodetic data and reservoir level fluctuations

Abstract

Monitoring has proved to be crucial for the safety of dams. Geodetic methods play an important role on this. The aim of geodetic monitoring is the detection of any change on the dam geometry as well as any displacements of its foundations. Despite the fact that dams are systematically monitored for the last decades, long-term monitoring records and their analyses are extremely rare in the literature. The majority of available data cover only the period of the first filling or a few years later (< 10 years). The aim of this study was the analysis of the geodetic monitoring record of Kremasta Dam, one of the highest earthfill dams in Europe (160m high and 456m long) for the first time after its construction. The available data cover a period of > 35 years (1966 – 2003) and consist of the horizontal deflections and vertical displacements of 25 control stations established on the crest and the body of the dam relative to reference points on stable ground as well as the reservoir level fluc ...
