Abstract: The channel improvement project located on the Hocking River in Athens, Ohio is estimated to have prevented over 68 million dollars in flood damages since its completion in 1971. However, sediment deposition has occurred in the channel since the construction of the project. The local sponsor of the project, the Hocking Conservancy District, has experienced extensive maintenance costs in attempting to maintain the design dimensions of the project. The Huntington District of the U.S. Army Corps of Engineers has investigated possible alternatives to the continuation of current dredging requirements. A hydraulic and sediment transport analysis was conducted on both the existing conditions, as well as on a number of alternatives to determine the relative performance and functionality of the LPP under different conditions. This analysis has been in the form of the Corps computer models, HEC-2 and HEC-6, along with site reconnaissance and engineering judgement. The current paper outlines the methodology used during this study.
