South Jetty Stability Study, Masonboro Inlet, North Carolina; Hydraulic Model Investigation.
Abstract
Hydraulic model flume tests were conduced to investigate the stability response of a jetty cross section proposed for the South Jetty, Masonboro Inlet, North Carolina. The original design (Plan 1) was not stable, and three additional designs were tested in an effort to find a satisfactory solution. All designs tested consist of one layer of armor stone subjected to breaking wave conditions. None of the designs were completely stable for all the designated storm conditions, and sufficient funds were not available to further the investigation. Based on the tests conducted, results show that all the designs were stable for storm conditions at the +8.5 ft mllw swl, but none of the designs were stable for storm conditions at the +12.5 ft mllw swl. Thus, whether the designs tested meet the no-damage criteria depends upon the selection of the design storm condition. (Author)
