Although often ignored due to their small size and seeming lack of economic importance, headwater streams have a high ecological importance to watersheds. Although restoration efforts on both streams and rivers have increased in recent years, monitoring on smaller successful and unsuccessful restoration strategies. The purpose of this study is to use macroinvertebrate bioassessment protocols to monitor and gauge the success of a restoration on a flood impaired headwater stream, Smith's Run, within a highly urban watershed.

Electronic Olfactory System (EOS) sensor technology is widely used in both research and industry to provide olfactory data for analysis. A variety of physical sensor types exist, each gathering olfactory data in a unique way, and each with individual performance gains and losses. This data has allowed the development of robotic platforms that utilize a variety of algorithms to locate and navigate to the sources of odor plumes in experimental environments. Most of these systems utilize chemotaxis, which allows effective navigation only in ideal, non-turbid environments due to both plume dynamics and limitations in response and recovery times of available artificial olfactory sensors.
