Navigation Conditions at Lock and Dam No. 4, Arkansas River. Hydraulic Model Investigation.

Abstract

Lock and Dam No. 4 will consist of a 110- by 600-ft lock and a 1190-ft long, gated, nonnavigable dam. A 1:120-scale fixed-bed model, reproducing 5.2 miles of the Arkansas River, was used to: (a) demonstrate flow conditions in lock approaches and in vicinity of Rob Roy Bridge (1.3 miles above lock); (b) determine effect of various guard wall designs on forces affecting tows in upper lock approach; (c) determine optimum location of harbor and dock, and mooring facilities; (d) measure distribution of different flows throughout the model; and (e) furnish information for use in developing modifications of the approaches and structures to improve navigation conditions. Tests were concerned with study of flow patterns, measurement of velocities in lock approaches, and behavior of a model tow on entering and leaving the locks and navigating through Rob Roy Bridge under flows ranging from 100,000 to 350,000 cfs.
