Abstract: The U.S. Army Corps of Engineers has completed the preliminary design of the outlet works for the proposed Seven Oaks Dam. The dam is the upstream-most feature of the Corps' Santa Ana River project. The outlet works design addresses heavy sedimentation accumulating gradually over time against the intake tower, potential for large quantities of floating debris, severe failure scenarios due to seismic conditions, and a difficult operating schedule requiring the ability to make small releases at high heads and to make a wide range of releases for any given head. The design also addresses provision for air supply and energy dissipation for discharges of up to 8000 cubic feet/second with velocities as high as 167 feet/second downstream of the regulating outlet gates.
