Process-based restoration of fluvial systems removes human constraints on nature to promote ecological recovery. By freeing natural processes, a resilient ecosystem may be restored with minimal corrective intervention. However, there is a lack of meaningful design criteria to allow designers to evaluate whether a project is likely to achieve process-based restoration objectives. We describe four design criteria to evaluate a project's potential: the expansion of fluvial process space and connectivity lost because of human alterations, the use of intrinsic natural energy to do the work of restoration, the use of native materials that do not overstabilize project elements, and the explicit incorporation of time and adaptive management into project design to place sites on recovery trajectories as opposed to attempts to “restore” sites via a single intervention. Applications include stream and infrastructure design and low-carbon construction. An example is presented in California's Sierra Nevada foothills.

基于过程的河流系统修复的设计标准

基于过程的河流系统恢复消除了人类对自然的限制，以促进生态恢复。通过释放自然过程，可以通过最少的纠正干预来恢复具有弹性的生态系统。然而，缺乏有意义的设计标准来让设计师评估一个项目是否有可能实现基于过程的修复目标。我们描述了四个设计标准来评估项目的潜力：河流过程空间的扩展和由于人为改变而失去的连通性，使用内在的自然能量进行修复工作，使用不会过度稳定项目元素的本地材料，并将时间和适应性管理明确纳入项目设计中，以将站点置于恢复轨迹上，而不是试图通过单一干预来“恢复”站点。应用包括河流和基础设施设计以及低碳建设。加利福尼亚的内华达山脉山麓就是一个例子。
