This phase of the model investigation of St. Louis Harbor was concerned with shoaling along the city front and at the lower entrance to the Chain of Rocks Canal. During unusually low river stages, less-than-project depths had been occurring at docks and terminals along the city front. Difficulties encountered during these low-flow periods led to the authorization of studies and investigations to determine the advisability of providing improved, commercial harbor facilities at and in the vicinity of St. Louis, Missouri. The purposes of the model study were to determine the causes of the shoaling in the harbor and docking areas and to develop plans that could be used to eliminate or reduce shoaling in these areas and in the lower entrance to the Chain of Rocks Canal. The model used in the investigation was of the movable-bed type, constructed to scales of 1250 horizontal and 1100 vertical and reproducing the reach of the Mississippi River and adjacent overbank areas between miles 191.0 and 169.9.
