The proposed Comite River Diversion Project was designed to lower flood stages along the Comite and Amite Rivers by diverting Comite River flood flows to the Mississippi River. Previous hydraulic models were used to help develop the diversion plan. The hydraulic requirements for the diversion channel stage control structure (also referred to as the Lilly Bayou structure) that were developed in the previous study changed, and another hydraulic model was necessary to verify the performance of the new design. A satisfactory design for the Lilly Bayou structure was developed using a 1:36-scale hydraulic model. The model reproduced 112.78 m (370 ft) of the approach channel, the weir crest, spillway, and stilling basin, and approximately 243.84 m (800 ft) of the outflow channel. Modifications which consisted of lowering the weir crest, lowering the stilling basin floor, and changing the side slopes in the approach channel from 1V on 3H to 1V on 3.5H were made to achieve the desired hydraulic performance.
