Navigation Conditions at Locks and Dam No. 4 Monongahela River, Pennsylvania.
Abstract
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.
