Morganza Floodway Control Structure, Mississippi River: Hydraulic Model Investigation
Abstract
Model investigations of the control structure for the Morganza Floodway were conducted to examine the over-all performance of the structure with particular attention to discharge coefficients, flow at the abutments, and energy dissipation. Three models were used in this study: a 1:16-scale model reproducing five gate bays and the right abutment of the structure as originally designed; a 1:30-scale section model reproducing two full and two half bays; and a 1:20-scale model reproducing five bays and the right abutment of a combined control-railway-highway structure. Test results indicated the desirability of using a 5-ft-wide broad-crested weir; flared training walls extending above the maximum expected water surface at the abutments; and a horizontal apron supporting two rows of baffle piers and terminated by a 4-ft-high sloping end sill.
