Resistance of Barge Tows Model and Prototype Investigations; Civil Works Investigations 814 and 835
Abstract
Model tests were conducted at 1:36-scale ratios in restricted, shoal, and nonrestricted straight channels to investigate channel effects on resistance of barge tows. The restricted channel widths varied from 125 to 300 ft with 1- on-2 side slopes, the shoal channels were 540 ft wide with vertical slopes; depths in both channels varied from 6.5 to 30 ft. The nonrestricted channels were 792 ft wide by 342 ft deep. Seven different sizes and shapes of barges were tested in flotillas of one to eight similar barges loaded to the same draft. Some of the tests simulated field tests. Comparisons of model and prototype data indicate speeds predicted from model tests conformed generally with those observed in field tests. Relations were developed for shoal and restricted channels to indicate relative effects of channel dimensions on flotilla performance. An equation was developed to evaluate flotilla performance in deep water.
