Book excerpt: Model tests of channel control structures constructed of concrete and gabions were conducted at an undistorted scale ratio of 1:12 to determine the discharge characteristics of the structures, size and extent of riprap required to prevent scour downstream of the structures, effects of ice flowing over the structures, and stability of the gabion structures. The gabion structure (type I) was located in a typical section of trapezoidal channel and a stable gabion configuration was developed by extending the gabion farther up the side slopes and farther downstream of the structure than was indicated in the original design. The concrete structure (type III) was placed in an expanded section of trapezoidal channel with riprap protection on the side slopes and on the channel bottom upstream and downstream of the structures. Model results indicated that the original size and extent of protection could be reduced without endangering the structure. Free and submerged flow discharge characteristics were determined for both types of channel control structures tested, and stability criteria were developed for the gabion structures. (Author).
