Dam breach would bring great loss to people’s life and properties, further, loss assessment of dam breach is an important part of dam risk management, which can provide important theoretical support for risk decision-making. In this study, the research progress of dam breach induced loss around the world was introduced, respectively for loss of life, economic loss, and ecologicalloss. According to the comparison of the evaluation indicators and simulation results for each loss assessment model, the advantages and disadvantages of the established models were studied. Simultaneously, the limitations of objective factors such as lack of measured data on dam breach loss assessment were discussed; in addition, some advices were put forward for the future research work. It is pointed out that: the reliability of basic data is crucial to the establishment and validation of dam failure loss assessment methods, and the lack of historical dam failure data and confusing records also restrict the establishment of assessment methods; the distillation and analysis of various loss influencing factors are the basis of dam failure loss assessment, and the quantification process of influencing factors also has an important impact on the reliability and accuracy of assessment models; the current domestic and international studies on dam failure loss of life and economic loss are mainly based on static indicators. The current studies on the loss of life and economic loss of dam failure at home and abroad are mainly based on static indicators, but the influence of human intervention to the assessment results of dam failure loss should be fully considered, and the dynamics of the dam failure evacuation system can be studied based on human behavior and social organization mechanisms to explore the quantitative relationship between dynamic indicators and dam failure loss, and to establish a comprehensive index system and dynamic assessment model for dam failure loss assessment.
