The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment transport capacity in the lower Southwest Pass of the Mississippi River. The study area was limited to the lower 4 miles of the Pass. A high flow representing 900,000 cubic feet per second at Venice, Louisiana, was selected for analysis. A high resolution finite element mesh that allowed detailed evaluation of velocity vectors was used to analyze seven alternative plans. This relatively quick and inexpensive analysis technique resulted in an optimal structural plan which provided maximum channel velocities at a minimal cost.
