The Resistance of a Barge Tow Moving in Shallow Water
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 112, Issue 4
Abstract
Estimating barge tow resistance in shallow water by Howe's formula can lead to an error in estimating the tow speed of large tows. While not enough published data is available to update Howe's formula, it is worthwhile to have an accurate formula for typical barge tows. The present note addresses this deficiency by presenting a comparison of the actual barge tow resistance given by estimates made using Howe's formula and the results from extrapolating the deep water resistance estimate using Schlicting's method. A two resistance augment is obtained and then introduced to Howe's equation for V > 6.0 mph to obtain accurate estimates for a 5 × 3 barge tow in waterdepth h = 16 ft (4.88 m).
