A mathematical model has been formulated to simulate the motion of a river barge flotilla maneuvering in an inland waterway. The mathematical model includes the inertial and hydrodynamic forces due to the motion of the flotilla through the water, as well as applied forces due to rudder and propeller action, wind and current effects. The layout of virtually any river channel boundaries, along with arbitrary wind and current speed and direction (including cross currents, non-uniform currents and eddys) can be easily described in the model coordinate system. In the present formulation, bank suction and shallow water effects are neglected. The mathematical model has been implemented in a FORTRAN computer program. The program is written to run in a conversational mode, periodically displaying the present status of the simulation to the user, and prompting for input of updated rudder and speed commands. The program has been structured to permit different tow characteristics and steering strategies to be evaluated with a minimum of difficulty. A sample program input deck and output listing are shown. This volume includes a program listing. (Author)
