Abstract: This report describes and gives results of a sedimentation study concerned with the development of improvement plans for the Loosahatchie-Memphis Reach of the Mississippi River, which is located about 740 river miles above Head of Passes. Frequent maintenance dredging has been required to maintain a navigation channel during low river stages in the area upstream of the Interstate 40 Highway bridge, and the left riverbank immediately downstream of Mud Island has a very low stability ratio. A movable-bed model reproducing approximately 18 km (11 miles) of the river to a horizontal scale of 1:300 and a vertical scale of 1:100 with crushed coal as the bed material was used to develop plans that would improve and stabilize the channel through the reach and the stability of the left riverbank. The model results indicated that an improved channel cou!d be maintained with the proposed dike plan, but that a berm on the left bank would be required to protect its stability.
