| Abstract: | The Moose Creek project includes an earth fill dam, outlet works on the Chena River, and a diversion channel which diverts Chena River floodflows into the Tanana River. The report presents results of hydraulic model studies conducted to support final design of the outlet works and the diversion channel. Sixteen alternate designs were tested in development of the outlet works. These designs were complicated due to the requirement to maintain fish and boat passage capability (to the maximum extent possible) during both gated and ungated operation of the structure and due to the lack of high-quality riprap required for channel protection downstream of the structure. Fixed- and movable-bed models were used in the diversion channel studies. Primary emphasis was placed on evaluation of scour adjacent to bridge piers and on development of the overflow sill at the downstream end of the diversion channel where it enters the Tanana River. The overflow sill at the downstream end of the diversion channel was developed through the use of a 1:12-scale movable-bed model. |
