Source: https://erdc-library.erdc.dren.mil/jspui/ Maintenance of Southwest Pass, one of the three major outlets of the Mississippi River, is a continuing and expensive problem due to extensive shoaling, primarily near the ends of the jetties and, to some extent, throughout the entire length of the pass. This report and Appendix A present the results of the model studies conducted to determine the effectiveness of proposed plans (e.g., lateral spur dikes, sediment diversion channel, sediment basin, relocation of the jetty channel, lateral spur dike extensions, and friction chambers) for the elimination or reduction of maintenance dredging in Southwest Pass and in the jetty and bar channels. Results of tests of Report 2 and Appendix A indicate some slight reductions in overall channel shoaling. Most of the test results indicate that there would be a redistribution of the shoal material in Southwest Pass; however, none of the plans tested caused movement of a significant quantity of shoal material into the Gulf._x000D_ _x000D_ NOTE: This file is large.
