Periodic Inspection of Jetties at Manasquan Inlet, New Jersey. Report 1. Armor Unit Monitoring for Period 1984-1994.
Abstract
Under the Periodic Inspections work unit of the Monitoring Completed Coastal Projects Program, precise locations of dolos armor units on the Manasquan Inlet, New Jersey, jetty heads were established and compared with data obtained previously. The vertical and horizontal positions of the dolos were defined through limited ground surveys, low-altitude aerial photography, and photogrammetric analysis. Broken dolos armor units also were documented. Even though horizontal and vertical movements have occurred, the jetties appear to be in good structural condition and are functioning as intended. There are areas at the heads of each structure that require additional dolosse to maintain the design cross section. The site will be revisited periodically in the future and the long-terrn response of the breakwater to its environment will be tracked. These periodic data sets are used to improve knowledge in design, construction, and maintenance of the existing structure as well as proposed future coastal projects. (MM)
