Many river rehabilitation projects have been implemented in the past 30 years, strengthening the natural dynamics and ecology of river systems, while reconciling the functions of flood protection, navigation, sediment extraction, and cultural identity. Still, the planning and design of floodplain projects is subject to debate on how to best follow the “natural” characteristics of specific river stretches, the “DNA of the river.” Unlike many other approaches of integrated river management, this approach entails a design strategy for spatial quality in river floodplain development projects at local and regional level, where the current discharge characteristics of the upstream river basin are taken as given. Starting point is the landscape ecological basis of the river, defining the characteristic (hydro‐morphological) processes and geomorphological/geological structures in each stretch of the river and floodplain area. An in‐depth characterization of these structures and processes helps design floodplains that can accommodate the various river management and development objectives. Often economically strong functions, like flood protection, can be partnered with weaker ones, such as ecosystem restoration. To safeguard spatial quality and sustainability in these integrated projects, the governance aspect is essential. Therefore the Smart Rivers approach addresses both substantial aspects (the “DNA of the River”) as well as procedural and governance elements (called the “Quality Relay”). The principles of the approach are applicable to project design along regulated rivers in densely populated areas all over the world.

Smart Rivers方法:基于河流DNA的防洪和洪泛区修复项目的空间质量

在过去的30年中,已经实施了许多河流修复项目,以增强河流系统的自然动力和生态,同时兼顾防洪,航行,沉积物提取和文化特征的功能。尽管如此,洪泛区项目的规划和设计仍在辩论中,即如何最好地遵循特定河段的“自然”特征,即“河中的DNA”。与许多其他综合河流管理方法不同,该方法需要在地方和区域层面制定河流洪泛区开发项目的空间质量设计策略,其中给出了上游流域的当前排放特征。起点是河流的景观生态基础,定义河流和洪泛区每一段的特征(水文形态)过程和地貌/地质结构。这些结构和过程的深入表征有助于设计洪泛区,以适应各种河流管理和开发目标。经济上的强大功能(如防洪)通常可以与较弱的功能(如生态系统恢复)配合使用。为了在这些综合项目中维护空间质量和可持续性,治理方面至关重要。因此,“智能河流”方法既处理实质性方面(“河流的DNA”),又处理程序和治理元素(称为“质量中继”)。
