Abstract:

This report summarizes a mathematical model study of water motions in two horizontal dimensions for Masonboro Inlet, North Carolina. The study was part of the Corps of Engineers General Investigation of Tidal Inlets research program GITI and was designed to meet two primary objectives. The first objective was to evaluate the effectiveness of state-of-the-art physical and mathematical modeling techniques in predicting the effects of major changes to an inlet on the hydraulics of the inlet. A second objective was to determine whether simple model tests, performed quickly and for a reasonable cost, could be relied on to evaluate the design of inlet improvements. Masonboro Inlet was in a natural state until August 1965, when major manmade changes to the inlet were initiated. By July 1966, construction of a weir jetty and dredging of a deposition basin and navigation channel had been completed. The mathematical and physical models were initially calibrated using bathymetric and hydraulic data collected at the inlet in September 1969. Selected parts of the calibrated model were subsequently remolded for prediction of hydraulic characteristics for the following conditions a preproject undeveloped inlet conditions, November 1964 bathymetry and b modified inlet and north jetty conditions, July 1966 bathymetry. Results of the mathematical model investigations are discussed in this report. Author
