Abstract: The Winfield lockage facilities currently consist of two 360-ft X 56-ft chambers with a normal lift of 28 ft. With the increasing traffic on the Kanawha River, these facilities are no longer adequate to serve the towing industry using this portion of the inland waterway system. Excessive delays now occur at Winfield and if the predicted traffic growth materializes during the next 10 or 15 years without action being taken by the Corps to address the problem, transfers of traffic movements to other more costly modes of transportation will result. Accordingly, studies were conducted to determine the capacity of the existing lockage facilities and to evaluate possible solutions for increasing this capacity through the use of alternative operating policies and rules that have been considered to be beneficial at other lock sites. Using the two simulation models, TOWGEN and WATSIM IV, the following four alternative operating policies were simulated to determine their respective effects on the capacity of Winfield and the delays to be expected should such policies be possible: (A.) First In-First Out (FIFO) Unrestricted. (B.) FIFO Unrestricted with a 10 percent reduction in lockage component times. (C.) FIFO Ready-to-Serve. (D.) 3 Up-3 Down, Unrestricted. These operating policies are discussed in detail in the report. Input data for the models were collected through the Performance Monitoring System (PMS) of the Inland Navigation Systems Analysis (INSA) program. The report includes discussions of model calibration and the criteria employed to analyze the capacity of the lockage facility based on the best available projections of future tonnage levels. Numerous capacity curves were developed to show the relationship between increasing commodity tonnages, tow delays, and lock utilization.
