This supplement presents modifications of the channels, jetties and weir system that were previously submitted for approval. The major revisions occurred as a result of model test data developed by WES subsequent to submission of the GDM. Other changes were made as a result of a conference held at SAD on 20 August 1976 concerning design of weir jetty structures. This supplement covers changes in jetty and channel configuration resulting from model testing of Plans 7A, 7B, Plans 1B through 1H and from innovative changes in weir system design. It also presents a summary of the WES model results for all plans tested. A comprehensive report of the model testing program for the Murrells Inlet Navigation Project will be submitted as a separate appendix to the General Design Memorandum at a latter date. A revised project cost estimate considering the various changes is presented. A physical model of Murrells Inlet and estuary was constructed at WES to evaluate the effects of currents and wave action on different arrangements of the jetty system under simulated prototype conditions. This fixed bed model was constructed to 1200 horizontal and 160 vertical scales.
