Abstract
The objective of this project is to design a restoration plan to restore function to 1,100 feet of stream in Sparta, Tennessee. The body of water in question is a small headwater stream that flows through a subdivision development project. A hydrologic study was conducted to determine the range of flow rates expected in the stream for use in the design parameters. Natural streams have features such as riffles and pools as well as a meandering pattern in plan form. These features sustain a diverse aquatic habitat by creating variable hydraulic conditions in the stream. A new stream channel was designed that included riffle and pool cross sections, a meandering planform geometry, and a longitudinal profile. Statistical relationships from a headwater stream characteristic database were used to determine channel geometry for riffle and pool sections. This geometry was then compared to survey data from an undisturbed section of the stream. A hydraulic analysis of the final stream design was completed to verify it functioned as designed and would be stable during flood events. Following this analysis, the design was ready to be implemented.
