FEASIBILITY STUDY OF A NUMERICAL TOW MODEL

The objective of the study described in this report was to explore the feasibility of developing a numerical hydrodynamic model of a typical push towboat-barge combination for use in engineering planning and design studies. Such a model might be used to simulate tow movements in restricted waterways in critical river reaches such as bends, bridges, and near navigation locks and dams to determine the adequacy and/or economic efficiency of channel designs. A literature search was conducted and it was found that no information was available at the beginning of this study on numerical models of tow hydrodynamics or on towing tank or prototype tests of the maneuverability of tows. During the course of the study several numerical models did become available and further research in this area was initiated by the U.S. Coast Guard Research and Development office. This work is described herein. It was found that it is feasible to predict tow maneuvers using a, numerical model of tow maneuverability; however, additional measurements of tow response characteristics are required before a model that would be useful in engineering studies can be developed. Comparisons of such a model with recent measurements of full-scale tow maneuvers could demonstrate the validity of this model.
