Abstract : Channel improvements of the Blue River, a right-bank tributary of the Missouri River, extend from its confluence with the Missouri River upstream for approximately 12 river miles. These improvements were designed to contain a discharge of 991 Cu m/sec (35,000 cfs) (a 30-year-frequency flood) with a coincident 10-year-frequency flood on the Missouri River. A grade control structure was designed as a three-stage weir. This structure was required to minimize erosion resulting from high velocities at the upstream end of the improved channel and the confluence with the unmodified channel and was located downstream of Byram's Ford and the Big Blue Battleground, a Civil War historic area nominated to the National Register of Historic Places in October 1989. A horizontal apron with baffle blocks and an end sill dissipated energy. The model study was conducted to determine how much flood protection could be provided in the Byram's Ford Industrial Park without adversely affecting cultural values of the historic site, reproduce the natural channel rating curve, examine energy dissipation problems expected downstream of the grade control structure, and determine the impact of the grade control structure on velocities and flow conditions at the Byram's Ford Civil War Crossing and riprap requirements for protection upstream and downstream of the structure.
