摘要

Channel improvements are a common means of providing flood protection for many communities, Many older channel improvement projects consisted of enlarging the existing channel cross section in order to increase conveyance. While this technique proved to be effective in lowering flood depths, the associated reduction in channel velocities often cause these projects to be susceptible to sediment deposition. As a result, excessive maintenance dredging is then required to maintain the design conveyance. One such local flood protection project is located on the Hocking RIver in Athens, Ohio. Since this project was completed in 1971, approxiamtely 95,000 yd~3 of material has been removed from the channel at a cost in excess of
