Description:
Source: https://erdc-library.erdc.dren.mil/jspui/ ; The Mobile Bay model was a fixed-bed model constructed to linear scale ratios of 1:1000 horizontally and 1:100 vertically. As shown in Plate 1, the model reproduced about 268 square miles of the Gulf of Mexico from Pine Beach on the east to about the west end of Dauphin Island, and in a southerly direction to about the -70-ft contour in the Gulf; all of Mobile and Bon Secour Bays; a portion of Mississippi Sound; and the Mobile and Tensaw Rivers and adjacent marshes to the junction of the two rivers at Mt . Vernon, some 40 miles upstream from Mobile. The model was equipped with the necessary appurtenances for accurate reproduction and measurement of tides, tidal currents, salinities, freshwater inflows, density effects, and other important prototype phenomena. The purpose of the model study was to determine the impact of a proposed access channel, referred to as Theodore Ship Channel, and the necessary islands designed to hold the initial construction material and subsequent maintenance dredging on salinities and flow patterns with special interest centered on the oyster industry at the lower end of Mobile Bay. The Theodore Ship Channel connects the existing bay navigation channel and the Theodore Industrial area. Verification tests were conducted to make certain that the model hydraulic and salinity regimens agreed with those of the prototype. The agreements attained between similar model and prototype values were considered satisfactory. The test results consist of comparable measurements of tide heights, current velocities, salinities, surface current patterns, and dye dispersion patterns for existing and proposed conditions. There were nine suggested configurations for the disposal areas, and an abbreviated testing program was first conducted to select the best configuration for complete testing. An analysis of the results of the bottom salinity comparisons of the abbreviated model tests led to the conclusion that for disposal areas west of the main ...
