使用孤立事件模拟模型进行洪水估算需要选择设计风暴和先决条件的合适组合。目前雨水排水设计的做法是任意采用暴雨持续时间、剖面和集水区湿度，并假设降雨深度和洪峰的重现期相等。本文描述了如何使用敏感性分析来检查降雨和洪水回复期之间的关系，从而系统地确定一组合适的设计输入，这些设计输入给出了所需回复期的峰值径流。这个过程允许这个特定的模型在设计和仿真中充满信心地使用。
Flood estimation using isolated event simulation models requires selection of a suitable combination of design storm and antecedent conditions. Current practice in storm drainage design is to adopt arbitrarily a storm duration, profile, and catchment wetness and to assume that the return periods of rainfall depth and flood peak are equal. This paper describes how sensitivity analysis may be used to examine the relationship between rainfall and flood return periods and, thereby, to determine systematically a suitable set of design inputs which give a peak runoff of the required return period. This process permits this particular model to be used with confidence in design as well as in simulation.
