洪水序列中混合分布的可能性已被广泛认可，并鼓励尝试将记录分离为同质子集。气候经常被认为是混合分布的一个来源，但将洪水记录分为气候亚组往往侧重于季节划分或将洪水系列划分为降雨和融雪产生的事件。在这项研究中，一个详细的水文气候分析被用来分类洪水的基础上产生的天气模式。这一程序是首次尝试对每个事件的洪水生成机制进行分类。该技术通过使用独立于径流系列的基于物理的信息来识别混合分布，而不是通过基于父分布本身的形状来定义子群体。
The possibility of mixed distributions in flood series is widely recognized and attempts to separate records into homogeneous subsets have been encouraged. climatic is often proposed as a source of mixed distributions, but the separation of flood records into climatic subgroubs has tended to focus on seasonal divisions or a partitioning of the flood series into rainfall and snowmelt-generated events. In this study, a detailed Hydroclimatic analysis is used to categorize floods on the basis of the synoptic weather patterns which produced them. This procedure represents the first attempt to the classify flood-generating mechanism responsible for each event. The technique identifies mixed distributions by using physically-based information that is independent of the runoff series, rather by defining subpopulations on the basis of the shape of the parent distribution itself.
