Book excerpt: Navigation improvements are being investigated for several existing projects on the Monongahela River. A hydraulic model study was conducted to evaluate filling and emptying system design alternatives and flow conditions in the upper and lower approaches for the lock replacements at Locks and Dam #4. A 1:25-scale model was constructed to determine the range of lock performance for both locks. The proposed filling and emptying system for the locks is an In-Chamber Longitudinal Culvert Filling and Emptying System. The filling time for acceptable chamber performance with the 6.035-m (19.8-ft) lift was 8.3 min. This filling time was achieved with a 3.0-min valve. The emptying time for the same lift was 8.75 min, and it was achieved with a valve time between 1.0 and 2.0 min. Experiments were also performed to measure the surge created in the vicinity of the proposed down- stream lock approach during emptying operations. Results showed that the water-surface elevation in the lower approach increased by 0.37 ft and occurred approximately 1.5 to 3.0 min into the emptying cycle.

Available in PDF, EPUB and Kindle. Book excerpt: Existing Locks and Dam No. 4 consist of two parallel locks with clear chamber dimensions of 56 by 720 ft and 56 by 360 ft and a fixed dam 540 ft long. Reconstruction of Dam 4 will involve replacement of the existing fixed dam with a nonnavigable-type gated dam with five 84-ft-wide gates and four 10-ft-wide piers. Provision will be made in the dam structure for ultimate replacement of the existing locks by two locks each 720 ft long, with one lock 84 ft wide and the other 110 ft wide. A 1:120 scale, fixed-bed model reproducing approximately 2.5 miles of the Monongahela River was used to determine the effect of the proposed reconstructed dam on flow conditions in the lock approaches with the existing and ultimate locks and for the development of modifications which might be required to provide satisfactory navigation conditions.
