Abstract : The Site 16 outlet works structure is typical of those that will be used for flood control in a series of 20 dams and reservoirs proposed for construction on tributaries of Papillion Creek within Douglas, Sarpy, and Washington Counties, NB. The recommended project plan for the Site 16 reservoir includes the construction of an earth dam, an uncontrolled spillway, and an uncontrolled outlet works consisting of an intake structure and conduit through the dam. A 1:7.5-scale model was used for specific study of the hydraulic performance to be anticipated with the Site 16 structure. In addition, a 1:10-scale model was used to determine generalized conditions required for the existence of flow control at entry to the riser shaft of similar outlet works structures.
