The major development of the Blue River Project is to use the existing tunnel to supply water to a penstock and turbine located in a proposed powerhouse. The flood release through the tunnel is presently discharged by open channel flow. After the modification, the outlet and a new gate structure will be pressurized to allow combined usage of hydropower and flood release. The velocity through the new gate will increase by almost 70 percent. A complex transition was designed to house the bifurcation to penstock and to the new dual gate structure. A comprehensive physical model study was conducted to examine the effectiveness of the transition. Turbulent pressure fluctuation tests and analyses were performed from upstream of the bifurcation through the new gates. A revised transition was designed to minimize any potential pressure fluctuation and cavitation problems.
