Abstract : The rubble-mound north jetty protecting the entrance to Yaquina Bay has experienced appreciable damage throughout its long service history. Since 1966 the north jetty has been rehabilitated twice after severe winter storm waves eroded the seawardmost 140 m (460 ft) of the jetty head. After the most recent rehabilitation in 1988 a 6-year jetty monitoring effort was initiated under the Corps of Engineers' Monitoring of Completed Coastal Projects Program. Principal purposes of the monitoring were to determine the likely cause for chronic damage to the Yaquina Bay north jetty, to improve monitoring methods for similar hostile environments, and to gain understanding of failure mechanisms associated with rubble-mounted structures.
