Abstract: The Steel Bayou and Little Sunflower Flood Control Drainage Structures are the two drainage structures of the Yazoo Backwater Project. They were completed in 1969 and 1975, respectively. The structures allow the storm water of the Mississippi Delta to pass through the open vertical lift gates into the Mississippi/Yazoo River when stages on the riverside of the levees are lower than the stages on the interior basin. When the stages of the Mississippi/Yazoo River are higher than the stages of the interior basin, the vertical lift gates are closed, keeping floodwaters from backing up into the South Delta. The Steel Bayou Drainage Structure is located 0.75 mile north of the Yazoo River mile 9.7 and has four vertical lift gates 23.5 ft high and 31 ft wide. The Little Sunflower Drainage Structure is located north of the Yazoo River at mile 32.6 and has two vertical lift gates 25 ft wide and 22.5 ft high. This report presents analytical and numerical calculations for the modification of the Steel Bayou stop logs to be used permanently at the Little Sunflower project. The calculations were conducted using the approach used to design miter gates horizontal girders using the 2001 criteria of the American Institute of Steel Construction (AISC) and the box girder calculations from the American Association of State Highways and Transportation Officials Load and Resistance Factor Design (LRFD) bridge manual.
