Abstract

Ten years of monitoring data are now available from the Crescent City dolos monitoring program. This extensive field data collection program was initiated in 1986, following the rehabilitation of the dolos section of the main stem of the Crescent City Outer Breakwater. The rehabilitation involved the placement of 680, fiber-reinforced, 38-tonne dolosse. Unique field monitoring techniques have been employed to collect data at Crescent City: movement data have been collected with ground-truthed, low-altitude (helicopter) photogrammetric survey techniques and stress data have been derived from strain gages mounted internally in select dolosse grouped together near the center of the dolos field. Results presented in this paper include 10 year histories on: wave climate, dolos movement/breakage, stress build up within dolosse, and concrete strength and fatigue. In addition, internal strain gage instrumentation verification test results are presented.
