The study evaluated the effect of inland navigation user charges on barge wheat movements on both the Mississippi River system and particular segments of the system. Transshipment models were constructed, examining three wheat varieties: hard red spring, hard red winter, and soft red winter. The models permitted two types of movements from producing to consuming areas--direct movements or movements through river transshipment points and foreign countries. Exports to any given point were allowed to move through any of several U.S. ports, depending upon relative transport costs. This gave the models a great deal of flexibility in the export sector, which is critically important for barge transportation of wheat. Data used included 1970-71 wheat production and consumption, and 1975 barge and rail rates, truck costs, and handling costs for each mode. User charges were based on 1974 operation and maintenance costs of the inland waterway system and 1974 barge ton-miles. Base solutions were obtained for each of the models, and then each was run with user charges recovering from 25 to 500 percent of annual operation and maintenance.
