Abstract : Tests were conducted in the fall of 1962 in Jackson Lock to investigate hawser forces resulting from hydraulic forces acting on a tow of loaded barges during lock filling and emptying operations. Jackson Lock was selected for these tests because the lock design had been model tested, and the lock has a typical side port filling system. The prototype tests were to provide data for comparison with model results and for use in developing lock design criteria. Measurements included hawser forces obtained from dynamometers installed in rigid and cable connections between the tow and floating bitts in the lock walls, culvert-valve openings obtained from potentiometers mounted on the culvert-valve operating arm, slope of the lock water surface measured with differential pressure transducers installed in the lock chamber ladder recesses, and tow movement obtained with potentiometers mounted on the landwall floating bitts.
