dc.descriptionAbstract: The Clarence Cannon Re-regulation Structure was reproduced in a 1:25-scale model to study ways of reducing scour downstream of the structure. The existing structure was designed according to criteria used for low-head navigation dams on the Arkansas River. This type of structure had a low ogee spillway and tainter gates. The model and testing conditions were reproduced according to prototype data received from the U.S. Army Engineer District, St. Louis. Experiments conducted on the existing structure showed that severe scour would occur at maximum discharge conditions. Baffle blocks and a shorter end sill placed on the existing stilling basin reduced the downstream scour. Additional stilling basin length, two rows of baffle blocks, and a shorter end sill almost eliminated the downstream scour. Due to downstream geologic conditions, the extended stilling basin was raised for constructibility purposes. The resulting design placed two rows of baffle blocks and the end sill on the raised extended stilling basin. Downstream scour levels with the raised basin design were also very low.-
