ABSTRACT
There are a few engineering structures that are in the design and operation so closely connected with the natural environment, such as embankment dams and levees. Due to the variability and randomness of natural factors (hydrology, geology, hydrogeology, morphology, properties and environment, etc.) they are unrepeatable and their occurrence in the same form and the same natural conditions is unrealistic. During the design phase, it is necessary to identify their development, mutual interconnections, the effect of time on their changes (particularly geotechnical properties), the effect of reservoir operation on the behaviour of dam etc. However, with their wide variability cannot be completely excluded differing behaviour of the hydraulic structure from the assumptions of the project. Some differences are discovered already during construction, others with the passage of time - in the period of the operation of the structure. In this paper are presented lessons learned and experiences from the operation of Starina dam. For clarification of anomalies have been applied special in-situ methods of measurements and statistical methods.
