BREACH PARAMETERS OF EMBANKMENT DAMS

摘要：

Dam risk analysis is at the heart of dam failures prevention and mitigation. In order to assess dam risk, it is essential to conduct a quantitative analysis of the process of dam breaching, which can be further subdivided into 1) predicting dam breaching parameters (e.g., breach geometry, breaching duration, and peak outflow rate) and 2) routing the outflow through the breach. The objectives of this study are 1) to develop robust empirical formulas for predicting dam breaching parameters based on past dam failure data and 2) to propose a simplified method for predicting the outflow hydrograph from the breach.
