WRRCTR No.117 An Automatic Hydraulic Structure to Open Sand Plugs at Stream Mouths on...
Numerous stream mouths on O'ahu are affected by sand berm blockages which prevent free flow of storm waters to the ocean and cause the stream water level to rise rapidly; often overflowing of the stream banks and flooding of adjacent land areas... 1978-06-01
