Abstract: 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.
