Abstract

The design of Oak Street Drain, a 3-mile-long rectangular open channel project in Corona, CA, requires a covered section with a sinuous alignment to avoid commercial development. The alignment includes a reverse 100-ft-radius curve and a long 200-ft-radius curve to convey the 100-year design flow of 7,100 cfs at velocities of 40 fps. A physical model was constructed to verify that the proposed design would pass the design flow without adverse hydraulic conditions.
