Steele Bayou Gravity Control Structure, Vicksburg, Mississippi. Hydraulic Model Investigation
The Steele Bayou gravity control structure is part of the Yazoo backwater project, which is a system of levees and channels designed to protect approximately 750,000 acres of alluvial lands from flooding by backwater of the Mississippi River. A hydraulic model was used to evaluate various schemes to eliminate the severe turbulence and eddies that have caused drastic erosion problems downstream of the Steele Bayou drainage structure. Significant bottom scouring and bank sloughing have occurred during the outflows following spring floods. The study was conducted to develop a solution for the excessive scour in the channel reach between Mississippi Highway Bridge No. 465 and the Steele Bayou structure where a 40-ft-deep by 600-ft-wide scour hole developed in the prototype. The longitudinal dikes, recommended as a result of the model tests, were installed in 1985 and have performed well through a period of relatively high water. Keywords: Rock dikes. (aw)
