Supplementary Tests for Masonboro Inlet Fixed-Bed Model. Hydraulic Model Investigation.
Abstract
This report describes supplemental tests of the Masonboro Inlet fixed-bed model not reported in 'Physical Model Simulation of the Hydraulics of Masonboro Inlet, North Carolina,' GITI Report 15. The supplemental tests consist of three separate studies performed in the Masonboro Inlet fixed-bed model. The first study examines the effects of the closing of various bay channels on the inlet's hydraulics. The second study examines the effects of the addition of a south jetty to the existing condition which has a single north jetty and examines the resulting hydraulics for various weir elevations on both jetties. The third study examines the use of a tracer material and closely parallels the hydraulic testing sequence discussed in the previous Masonboro Inlet report. The tracer tests include verification of the 1969-1971 shoaling trends, testing of the prejetty 1964 condition, testing of the single jetty plan with the 1964 bathymetry, and testing of the postjetty construction 1966 condition. These tests were performed to evaluate the effectiveness of using sediment tracer materials in inlet model studies. Results indicate the closure of any of the three interior channels in Masonboro Inlet produces a significant change in the inlet hydraulics and would most likely produce a significant change in morphology as illustrated by the prototype case history.
