Model study of the outlet structures for the Wappapello Dam
U.S. Army Engineer Waterways Experiment Station.
Syllabus: This memorandum constitutes a final report of the study performed at the U. S. Waterways Experiment Station on a model dam. The model was built undistorted to the linear scale ration, model-to-prototype, of 1 to 25. The general purpose of the model study was to check the hydraulic characteristics of all elements in the design of the outlet works, and to develop means of correcting any uneconomic, unsafe, or undesirable conditions. The results of the study indicated that the basic design of the outlet work was, for greater part, satisfactory. The single feature of the design offering greatest opportunity for improvement was the stilling basin. The model study indicated that a reduction of 64.5 ft. in the overall length of the stilling basin could be gained by effective combination of apron curvature, wing-wall alignment, and baffle-pier arrangement.
