Rapid determination of erosion model parameters is the premise of the evaluation of the burst flood in the emergency treatment of the barrier lake. The erosion rate was typically modeled with excess shear stress model and Wilson model. However, there is no unified understanding of the range of erodibility parameters. In order to study the relationship between the erodibility parameters of two models and soil properties and the range of erodibility parameters of various types of soils, quickly determine the erodibility parameters of the dam, a database of 279 test results were collected from the literature review as well as by contacting researchers and organizations working on erosion around the world in this paper. The samples were classified into coarse-grained and fine-grained soils according to the USCS. Correlation analysis and regression analysis of the data were used to obtain the relationship between the erodibility parameters and soil properties. Four measures were used to evaluate the statistical significance of the relationship between erodibility parameters and soil parameters for coarse-grained and fine-grained soils：R2、MSE、Fvalue/Fstatistic and Cross-validation. The erodibility parameters obtained from the experimental data were compared with the erodibility parameters predicted by the regression equation, the range of erosion parameters of different soil was obtained. Finally, taking Baige weir plug as an example, according to the erosion parameter database and statistical relationship established in this study, the erosion parameters and erosion rate were analyzed rapidly. The results show that this study can quickly determine the erosion parameters of the dam plug body, and provide help for rapid assessment of the risk of burst flood under emergency conditions.
