Navigation Channel Improvements, Barnegat Inlet, New Jersey: Hydraulic Model Investigation

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 characterization 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. (Modified author abstract)
