评价和比较了用于估计溃坝参数的分析技术。溃坝引发的潜在洪水的发展需要几个要素：水文情景、可能的溃坝模式、与溃坝模式相关的溃坝参数以及随后的流量过程线的路线和绘图。本文介绍了最近的研究使用和应用的几个溃坝参数估计来描述溃坝的物理特性，使用这些参数的非稳定流路由模型HEC-RAS，以及计算和显示所产生的下游影响。所使用的突破参数估计包括经验和堤防侵蚀过程模型。
Analytical techniques for the estimation of dam breach parameters were evaluated and compared. The development of potential flooding from a dam failure requires several elements; the hydrologic scenario, the possible dam failure modes, breach parameters that are associated with the failure modes, and the routing and mapping of the consequent discharge hydrograph. This paper presents recent research into the use and application of several dam breach parameter estimators to describe the physical characteristics of a dam breach, use of those parameters within the unsteady flow routing model HEC-RAS, and the computation and display of the resulting downstream impacts. The breach parameter estimators that were used include both empirical and embankment erosion process models.
