This report presents a plan for determining hydrodynamic coefficients of maneuvering simulation models for river towbarge flotillas from data collected during free-running maneuvering trials of the full-scale river tows themselves. The plan includes specification of motion sensor type and accuracy requirements and a schedule of maneuvers to be executed during trials. Simulation of the maneuvering trials and data collection indicates that the system identification statistical data processing technique can estimate hydrodynamic coefficients similar in form to those obtained from towing tank planar motion mechanism tests. Calculation of the sensitivity of definitive maneuvering characteristics to changes in hydrodynamic coefficients indicates coefficient estimation accuracy requirements. Author
