Over the past two decades there has been a significant advancement in the science of stream restoration. Much effort has been spent on understanding channel dimension, pattern and profile. However, not as much consideration has been given to understanding how stream functions influence channel dimension, pattern and profile. Harman et al. has produced the Stream Functions Pyramid Framework which addresses this issue and provides guidance on applications relevant to stream restoration. This presentation provides a case example of how the framework can be applied on a reach specific stream restoration project. The U.S. Fish & Wildlife Service used the Stream Functions Pyramid Framework to conduct functional and stability assessments, set quantifiable restoration goals and objectives, create design criteria and establish quantifiable monitoring performance standards for the Mossy Creek Stream Restoration Project, Augusta County, Virginia.
