Book Description
Lock and Dam No. 4 is the fourth lock in a series of five to be constructed on the Red River Waterway from the vicinity of Old River to Shreveport, LA. Lock 4 is located in a cutoff canal on the left descending bank about 169 post project river miles above the mouth of the Red River. The principal structures include an 84- by 785-ft lock, a gated spillway containing five tainter gates, and a hinged crest gate 100 ft wide. The fixed bed model reproduced about 3.5 miles of realigned river channel and adjacent overbank area at an undistorted model scale of 1:100. The model investigation was concerned with determining the effects on navigation through the study reach for the proposed design and developing modifications required to the design that would provide satisfactory navigation conditions.

Book Description
A movable-bed physical model was used to investigate and solve potential channel development and maintenance problems associated with Lock and Dam No. 4 on the Red River in Louisiana. The model reproduced the Red River from 1967 river mile 213.1 to 204.7 using a distorted scale of 1:120 horizontally and 1:80 vertically. The model was adjusted to reproduce prototype conditions before the inclusion of the proposed project. The upstream approach to Lock and Dam No. 4 will include a short-radius man-made cutoff through the neck of the existing bend, shortening the length of the existing bendway by approximately 1 mile. The lock and dam will also be located in an excavated channel, cutting off about 3 miles of an existing bendway. Procedures were developed to properly model channel modifications that significantly shorten the channel length. Various configurations of dikes and berms were evaluated to determine the optimum configuration for maintaining a satisfactory navigation channel.

Book Description
Lock and Dam No. 4 is proposed for construction in a cutoff canal on the Red River approximately 71 miles below Shreveport, LA. The principal structures consist of a lock with an adjacent gated spillway and overflow weir. The lock, which will be 84 ft wide with 685 ft of usable length, will be located on the left bank line looking downstream and will have a maximum lift of 25 ft. The gated spillway will contain four tainter gates, 60 ft wide by 36 ft high, with a sill elevation of 86.0 ft (elevations (el) are in feet referred to the National Geodetic Vertical Datum), and an overflow weir with three 100-ft-wide hinged gates. The crest of the hinge-gated weir will be at el 115.0, and the top of the hinged gate in its fully raised (closed) position will be at el 122.0. Tests were conducted in a 1:40-scale model of Lock and Dam No. 4 to develop a satisfactory energy dissipator and a stable riprap protection plan. The original crest was lowered to el 85, a fifth tainter gate was added, and the three 100- ft-wide hinge-gated crests were replaced by a single 100-ft-wide baffled chute. Tests were conducted to compare the two designs, and data obtained with both designs are presented in this report. Water-surface profiles were measured for the full range of expected operating conditions. The recommended stilling basin provides adequate energy dissipation for normal flow and for a single gate fully open and half open operating with minimum tailwater. The recommended riprap protection plan in the upstream and downstream areas adjacent to the structure remained stable for these conditions.
