| dc.description | Abstract: The South Fork of Tillatoba Creek, Mississippi, has experienced a relatively rapid stage of channel degradation accompanied by severe streambank erosion. A two-stage, reinforced-concrete grade-control structure is proposed for construction by the U.S. Department of Agriculture, Soil Conservation Service, on the South Fork of Tillatoba Creek. Tests were conducted on a 1:29-scale section model of the low-stage structure and a 1:25-scale model of the grade-control structures to verify design criteria, evaluate the hydraulic performance of the structures, and make modifications to the design, where needed, to improve performance. The 1:25-scale model reproduced both the high- and low-stage control structures, approximately a 500-ft length of the upstream approach, and an 1,100-ft length of the topography downstream from the structures. Flow conditions in the approach to the low-stage structure were improved with design modifications. Energy dissipation in the low-stage structure stilling basin was improved by the addition of a trajectory curve type of drop. Approach wing walls improved flow conditions in the high- and low-stage structure stilling basins. The widths of the exit channels for both the high- and low-stage structures were reduced from their original design. Improvements were made to flow conditions in the high-stage structure exit channel by eliminating the preformed scour hole, and stable riprap designs were determined. | - |
