Performance criteria of rockfill embankment dams are based on theresponse to external loadings, such as external and internal water pressures,gravity forces, and in particular earthquakes, which can be considered as themost severe form of structural loads. These criteria can be quantified and areoften expressed as limiting values. Dams whose performance may exceedspecified criteria for a certain hazard may be deficient with respect to their safety.Performance assessment, on the other hand requires direct and systematicobservation of the dam to loadings and compare these with pre-establisheddesign criteria. This paper focusses on the performance of rockfill dams (damswith central impervious core and concrete face rockfill dams) and their responseto multiple seismic hazards….
