We suggest an adaptive model framework named CAOS (Catchments As Organized Systems) that is based on elementary functional units (EFUs), which are regarded as homogeneous with respect to their hydrological functioning. These EFUs are arranged along time invariant lead structures in the landscape such as the catena. Depending on the prevailing boundary conditions, their internal states and external drivers, EFUs will be grouped into sets named dynamic functional units (DFUs). DFUs are deemed to function similarly with respect to the processes and structures that dominate either energy exchange or, under rainfall-driven conditions, vertical and lateral flow processes. Thus, dynamics in the entire set can be represented by simulating dynamics for a single or a few representatives. This will reduce computational effort to a minimum amount and ideally allows application of the CAOS model for improving hydrological practice at the lower mesoscale. Most of the necessary process descriptions for the model objects will be iteratively refined based on growing insights and growing data sets in the individual sub projects. Project S will furthermore develop and maintain structures to manage all data required for and produced by the research unit and organise frequent meetings to sustain knowledge transfer among the participating projects.

我们建议一个基于基本功能单元（EFUS）的自适应模型框架（流域为有组织的系统），该框架在其水文功能方面被认为是同质的。这些EFU在景观（例如Catena）中的时代不变铅结构中排列。根据主要的边界条件，其内部状态和外部驱动器，EFU将分为名为“动态功能单元”（DFU）的集合。 DFU被视为在能量交换或在降雨驱动的条件下垂直和横向流动过程的过程和结构相似的功能相似。因此，可以通过模拟单个或几个代表的动力学来表示整个集合中的动力学。这将最少减少计算工作量，并理想地允许应用CAOS模型来改善低中尺度的水文实践。模型对象的大多数必要过程描述将根据不断增长的见解和各个子项目中不断增长的数据集进行迭代完善。项目S还将开发和维护结构，以管理研究部门所需和生成的所有数据，并组织频繁的会议以维持参与项目之间的知识转移。
