Tests were conducted on an undistorted, 1:20- scale physical model of the high-velocity channel for Waimano Stream to determine the adequacy of the sinuous channel to pass discharges as large as 6300 cfs. Since right-of-way limitations prevented major realignment of the proposed channel, superelevated curves were more severe than those recommended by current design guidance. The entering transition section was modified to improve flow conditions. Also, the superelevation was increased and the curve design modified in several locations to improve flow distribution. The Moanalua Road drains were modified to improve flow conditions at their confluence with the main channel and the entrances to the relief drain and the diversion channel were modified to facilitate passage of the required flows.
