Hydraulic model study of the Spring Creek debris dam selective withdrawal system. Final report
The Bureau of Reclamation is designing a selective withdrawal outlet works structure as part of the modifications to Spring Creek Debris Dam. The selective withdrawal structure will be used to discharge varying concentrations of pollutants from the reservoir and to decrease the frequency of releases from the existing spillway. The hydraulic model study was used to determine the losses through the system and operational limits on the submergence of the skimming weir and slide gates in order to maintain control with the downstream gates and to suppress vortex formation. Additional items that were investigated were flow conditions in the conduit with more than one slide gate discharging, pressures acting across the weir gate under large submergences, and conditions under which blowback of entrained air might occur.
