GITI Models for Masonboro Inlet 



148. As part of the GITI studies, Masonboro Inlet was a test case for 

 evaluation of physical and numerical models. Data collected on 12 September 

 1969 were used to calibrate the models, and data collected in July 1974 were 

 to be used for verification; however, the hydrography changed between the two 

 dates, and the same cross sections could not be used for verification. 

 Detailed analyses of the outputs from these models are given by Harris and 

 Bodine (1977); Masch, Brandes , and Reagan (1977); and McTamany (1982). All 

 models, except for the lumped-parameter model of Seelig, Harris, and 

 Herchenroder (1977), which will be referred to as the GITI Lumped- Parameter 

 Model (GLPM) , appear to be special-purpose models specifically designed to 

 describe Masonboro Inlet. As such, they may be considered outdated and
