Abstract: Locks and Dam No. 26 is located on the Mississippi River approximately 202. 9 river miles above the mouth of the Ohio River. This paper will discuss the utilization of a physical model located at the U. S. Army Corps of Engineers Waterways Experiment Station (WES), Vicksburg, Mississippi, to study the extent of removal of the existing Locks and Dam No. 26. Scenarios studied consisted of how much of the structure to remove, depth of removal, and sequence of removal. The model reproduces approximately 6. 7 miles of the Mississippi River to an undistorted scale of 1:120. Various stages and extent of removal were reproduced in the model, and the impacts these stages of removal would have no navigation and hydraulic conditions were studied.
