ABSTRACT
ABSTRACT: Dam resistance of concrete or masonry dams in overtopping condition has to be considered regarding the possible failure mechanisms. From this point of view indications provided by the analysis of the recorded failure (complete or partial) of dam cases appears very useful. In this paper available cases of gravity, buttresses and arch dam failures will be reviewed, pointing out the possible consequences in flood conditions of overtopping effects on dam or foundation stability conditions or the behaviour of mechanical components. Some cases will be examined and an attempt to draw some general features will be performed.
