Critical analysis of the capability of a proposed canalized waterway to economically move the tonnage of anticipated commerce is necessary, particularly in those instances where channel dimensions are limited and lock sitings are less than ideal. Plotting of probable vessel movements through the entire waterway, or critical reaches, by graphical means is a valuable tool in measuring waterway capacity. Essentially, the graphic method permits analysis of vessel movements by showing the position on the waterway of all vessels at any one time, and the trace of these movements show graphically interferences to movements and resultant delays for each and all vessels. Physical elements of a waterway may be evaluated in reference to the capability of each to perform in balance with the others. The total practical tonnage capacity of the waterway may be determined, and time of transit for vessels may be more accurately estimated to determine the cost of moving commodities through the waterway.
