The design of safe structures and installations is an important issue in hydraulic engineering. In this context, the question arises whether the concept of resilience can provide additional information compared with the (semi‐) probabilistic or risk‐based analysis to improve the results of the design procedure. In this paper, the integration of resilience aspects into the design is discussed on three levels: First the consideration of resilience as a characteristic of the structure and its members, secondly as a set of multicriterial indicators and thirdly as a numerical value. To illustrate the three resilience approaches three examples are discussed: the qualitative selection of components, reassessment of urban flood resilience on the basis of updated historical flood records and the comparison of resilience values for different hydraulic structures. Considerations on the quantitative description of the resilience of hydraulic structures in flood‐prone areas are presented and should open the way to further discussions about the quantification of resilience terms.

量化水利工程的复原力：洪水，洪水记录和市区的复原力

安全结构和装置的设计是水利工程中的重要问题。在这种情况下，与（半）概率分析或基于风险的分析相比，弹性概念是否可以提供更多信息，以改善设计程序的结果。在本文中，从三个层面讨论了将弹性方面集成到设计中：首先将弹性作为结构及其成员的特征，其次作为一组多指标指标，其次作为数值。为了说明这三种复原方法，我们讨论了以下三个示例：组件的定性选择，在更新的历史洪水记录以及不同水工建筑物的抗力值的比较的基础上，重新评估城市的抗洪能力。提出了对洪水多发地区水工建筑物的弹性进行定量描述的考虑因素，并应为进一步讨论弹性项量化问题开辟道路。
