Description: Technical report
Lock and Dam 19, Mississippi River is located on the right descending bank of the Mississippi River approximately 364.3 rivermiles above the mouth of the Ohio River at Keokuk, Iowa. A comprehensive model study was conducted for Lock and Dam 19 in order to accomplish the following: a. Determine the effects of proposed alternatives on navigation in the upper lock approach. b. Develop modifications that could improve navigation conditions. c. Evaluate navigation conditions for tows entering and leaving the upper lock approach. The model was a fixed-bed type with the overbank area and the channel molded of sand cement mortar to sheet metal templates set to the proper grade. The lock, power house, gated spillway, and the radial ice fender were constructed of sheet metal and plexiglass and set to the proper grade. The model demonstrated conditions resulting from various alternatives tested and satisfied design engineers and navigation interests of the design's acceptability. Based on the available data, the model reproduced with a reasonable degree of accuracy the conditions in the prototype. Flow patterns were studied, velocities and water-surface elevations were measured, and the effects of currents on the movement of a model tow entering and leaving the upper lock approach were monitored.
