Abstract
Previous research has delineated the University of Delaware (UD) Experimental Watershed for educational purposes and has determined that surrounding land use negatively impacts the streams in it. The purpose of this project is to conduct research into stream restoration techniques and collect the necessary data for restoration implementation on Fairfield Run in the UD Experimental Watershed. The researchers chose a reference stream reach and candidate sites for restoration. They then conducted water quality, habitat, and stream geomorphology surveys. This data was incorporated into stream restoration designs. The candidate restoration sites were found to be impaired in comparison to the reference condition in terms of both water quality and habitat. The restoration and reference stream reaches had similar geomorphology classifications. The researchers selected vortex rock weirs, branch packing, single vanes, tree revetments, stone toe protection, live stakes, and cross vanes from the restoration techniques for use on Fairfield Run. Many viable restoration techniques are available that utilize natural materials already found in the UD Experimental Watershed. Fairfield Run is impaired
and could be improved through use of some of these restoration techniques. Furthermore, its geomorphology classification suggests that it is a good candidate for restoration. The restoration project can be used to further the educational mission of the UD Experimental Watershed by involving students and the public in an effort to improve on-campus stream quality and watershed health.
