Abstract: The Gallipolis Locks and Dam are located on the Ohio River at mile 279.2 and include a 600- by 110-ft main chamber and a 360- by 110-ft auxiliary chamber. As a result of increasing traffic and tow sizes, these locks have become a serious bottleneck to vessel movement along one of the major arteries of the United States inland waterway system. This report includes the results of an investigation to determine the physical capacity of the existing Gallipolis Locks, considering both operational and minor structural changes that could possibly improve the locking efficiency at these locks. Several alternative operating policies, some requiring structural improvements, were analyzed and compared by employing the computerized TOWGEN/WATSIM (tow generator/waterway simulator) model package. Some proposed improvements were analyzed through the use of hand-computational and/or graphical techniques. The prototype data used in the investigation were collected and summarized through the Performance Monitoring System (PMS) of the Corps of Engineers Inland Navigation Systems Analysis (INSA) program. The report includes discussions of the data formats required by the model, calibration of the model, and analysis of model output. A number of capacity curves are presented to show the relation between increasing commodity tonnages, tow delays, and lock utilization. Lock capacity levels, in terms of tonnage per month and tonnage per year, are tabulated for convenient comparison of all potential operational and structural improvements. Appendix A presents file identification codes for use with WATSIM, and Appendix B contains a comparison of October and December 1975 PMS data taken at Gallipolis Locks and Dam. Specialized terms used in the report are listed and defined in Appendix C, and PMS commodity codes are listed and described in Appendix D.
