Abstract:

The sinkage, trim, and underkeel clearance of the lead barges in a 3 x 3 barge train were measured. The barges represented typical Mississippi River barges. The tests were conducted in response to a USCG request to investigate groundings due to channel depth decreases. The water depth varied from 2.6 to 1.05 times the barges draft. There were two bottom contours one with constant depth, and one with an underwater obstacle in the form of a step. The speed of the barge train was varied from 2 kts to 8 kts, full scale. Author
