| dc.description | Abstract: The model study of Barnegat Inlet was conducted to evaluate the effectiveness of proposed plans of improvements to stabilize the size and location of the authorized navigation channel through the inlet. Tests were conducted in a fixed-bed model to define the effects of each stage of a multistage plan of improvement on the hydraulic characteristics of the inlet. The model was then converted to a movable-bed model, and the effects of the multistage plan of improvement on the movement of material were defined. The results of the tests indicated that the key to the improvement of navigation conditions in the inlet is a new south jetty to be constructed essentially parallel to the existing north jetty. Tests were then conducted to evaluate the length and height of the twin jetties. Based on the results of the study, it is recommended that the following sequence of improvements be employed : Remove existing south jetty, working landward from the ocean end and leaving a short section of the jetty for beach stabilization. At the same time, construct the new south jetty. Use stone from old jetty in new jetty if it is economical. Prior to closure of the south channel by construction of the jetty, begin dredging a navigation channel of 300-ft width and 8-ft depth at mean low water on a line from deep water in the throat to a point midway between the ocean end of the existing jetties. Raise the north jetty to +8 ft mlw from the beach to a point 1200 ft from the ocean end of the jetty. Dredge a 300-ft-wide interior channel to a depth of 10 ft mlw on a line favoring deep water at the throat of the inlet bayward to deep water at the north end of the existing sand dike. Consider in sequence the groin field (stage 2) and sand dike (stage 4) should the interior channel subsequently prove to require excessive maintenance. NOTE: This file is large.
