River floods are extremely important to society because of their potential damage and fatalities. Floods are also very interesting research subjects because of the intriguing non-linear interactions and feedbacks involved, interesting issues of generalisation and the need for investigating them in an interdisciplinary way. Extreme floods are not very well understood to date but new, high resolution data and new concepts for quantifying interactions promise a major breakthrough of a body of research carried out in a coordinated way.The objective of this Research Group is to understand in a coherent way the atmospheric, catchment and river system processes and their interactions leading to extreme river floods and how these evolve in space and time. An innovative and coherent concept has been adopted in order to maximise the potential of the cooperation between the research partners which consists of three layers of integration:- research themes focusing on the science questions, - subprojects revolving around specific research tasks, and - a joint study object of extreme floods in Germany and Austria. Using scales as a binding element, the research plan is organised into the research themes of event processes, spatial (regional) variability, temporal (decadal) variability, and uncertainty and predictability. The members of the Research Group have been selected to obtain a team of leading experts with expertise that is complementary in terms of processes, methods and regional knowledge. The cooperation and communication strategy will be implemented through themed cluster groups, combining several subprojects, regular meetings of the cluster groups an annual project symposium and a data warehouse, facilitating data exchange on the joint study object. Equal opportunity policies will be adopted and female and early career scientists will be promoted in a major way. Overall, the outcomes of the Research Group will constitute a step change in the understanding of the coupled system of flood processes in the atmosphere, catchments and rivers which will have major implications for a range of sciences and the society.

河流洪水对社会极为重要，因为它们可能造成破坏和死亡。洪水也是非常有趣的研究课题，因为有趣的非线性相互作用和反馈，有趣的问题的概括和需要调查他们在跨学科的方式。迄今为止，人们对极端洪水的认识还不是很清楚，但新的、高分辨率的数据和量化相互作用的新概念有望使以协调方式开展的一系列研究取得重大突破。本研究组的目标是以连贯的方式了解导致极端河流洪水的大气、集水区和河流系统过程及其相互作用，以及这些过程在空间和时间上的演变。一个创新的和连贯的概念已被采用，以最大限度地发挥研究伙伴之间的合作潜力，其中包括三个层次的整合：-研究主题集中在科学问题，-围绕具体的研究任务的子项目，和-在德国和奥地利的极端洪水的联合研究对象。使用尺度作为约束性元素，研究计划被组织成事件过程，空间（区域）变化，时间（十年）变化，以及不确定性和可预测性的研究主题。挑选研究小组成员是为了组建一个由具有专门知识的主要专家组成的小组，这些专家在程序、方法和区域知识方面具有互补性。合作与交流战略将通过专题分组、若干分项目的合并、分组定期会议、年度项目专题讨论会和数据库来实施，以促进关于联合研究对象的数据交流。将采取平等机会政策，大力促进女性和初出茅庐的科学家。总的来说，研究小组的成果将构成对大气、集水区和河流中洪水过程耦合系统的理解的一个步骤性变化，这将对一系列科学和社会产生重大影响。
