A major portion of the inland waterway system of the United States consists of a series of locks and dams and the navigation pools maintained behind these dams. With this type of waterway, the locks often serve as the major constraint to the growth of waterborne traffic on the waterway system. Thus, the determination of the capacity of a lock, both the physical limit and the economic capacity, is an essential element in the planning and design of a waterway system. In the past several years, computerized simulation models have effectively been used in determining the physical capacities of locks in the waterway systems and have provided besic information for the analysis of the economic capacities of these locks. An example of the effective use of simulation modeling for this purpose is demonstrated by the analysis of Locks and Dam 26 (L&D 26), Mississippi River at Alton, Illinois, and the proposed replacement alternatives. L&D 26 has become a serious congestion point on the Mississippi River system and because of its strategic location will limit the growth of waterborne commerce on several major connecting waterway systems. Two simulation models, TOWGEN and WATSIM IV, were used conjunctively to analyze the physical capacity of the existing locks using various procedures for locking vessels. The sensitivity of this capacity determination to various factors was evaluated. Then the capacities of the replacement alternatives were determined in a similar manner to allow the selection of those alternatives that would service the projected traffic through the project life. The usefulness of these simulation models has been proven in several similar studies. These models are continuously being improved. Other simulation models and their supporting data bases are being developed under the ongoing Inland Navigation Systems Analysis (INSA) project of the Corps of Engineers.
