Greenville Bridge Reach is located on the Mississippi River from river mile 542 to mile 530. The Greenville reach affects tows navigating through the Highway 82 Bridge located at mile 531 approximately 12 miles downbound of Greenville, MS. Research conducted at the U.S. Army Engineer Research and Development Center (ERDC) suggested realignment of the channel through the reach and construction of seven bendway weirs would improve navigation conditions through the reach and existing Highway 82 Bridge. Although the general design of the project was based on model studies conducted at ERDC from 1979 to 1996 and sound engineering practices, channel alignment and bed configuration can vary somewhat from those predicted in model studies due to composition of the bed material and different flow conditions than those used in the model studies. Therefore, due to its complexity, this project was selected for monitoring under the Monitoring Completed Navigation Projects program. Various types of data were collected and analyzed to determine the effects of the improvements on navigation through the reach and identify any potential problems of alignment of navigation traffic approaching both the new (currently under construction) and old bridges. Bathymetric data were collected and used to compare the predicted channel to the developed channel. It was determined that the bendway weirs at Vancluse Bend above the Highway 82 Bridge at Greenville, MS, are performing as predicted.
