In 2014 the Dam Safety Research Group (SERPA) of the Technical University of Madrid performed several tests to assess the behavior of rockfill dams in overtopping scenarios. A structural failure pattern of the clay core was observed, as expected. Hence, it was concluded that a model to simulate the observed failure mechanisms was needed. The model described herein provides the first results on assessment of the clay core stability following failure of the downstream shell. The failure process may result in one or more brittle and abrupt breakage phases of the core, herein classified as structural breakages, as opposed to the progressive failure caused by the erosion of the cohesive material. Thus, total or partial failure of the clay core occurs when the acting forces reach one of the instability conditions: overturning or sliding. The model was utilized to retroactively analyze two experiments carried out in the laboratory; the results obtained were consistent with the experimental measurements. The model is based on simple mechanical principles, but represents a paradigm shift in the interpretation and evaluation of the overtopping failure processes, especially since it results in a failure hydrograph different from those typically adopted, and therefore, has repercussions in the development of emergency plans.
