Hydraulic Model Studies of Silver Jack Dam Spillway Stilling Basin, Bostwick Park Project, Colorado
A massive landslide destroyed the nearly completed spillway stilling basin at Silver Jack Dam in Colorado. A circular curve in an inclined plane was used to connect the undamaged approach conduit and the relocated stilling basin. Hydraulic model studies were performed to assure satisfactory flow conditions in the conduit and stilling basin under limited tailwater conditions and with unsymmetrical approach flow resulting from a circular curve in the upsteam conduit. A deflector vane was installed in the crown of the tunnel downstream from the curve to prevent the flow from crossing over the top and sealing the portal. Vanes were developed for the stilling basin approach chute to improve flow distribution in the basin. Unique baffle blocks were developed to provide good energy distribution in a basin that had insufficient tailwater depth to form a conventional hydraulic jump. Pressure measurements were made on the conduit bend, conduit vane, chute vanes, and baffle blocks. (Author)
