interior flows are studied by Model A and since the main purpose of Model B is 

 to study coastal processes in the region mostly exterior to the inlet. There- 

 fore, the calibration and verification of the tide model are complete and 

 successful. 



88. Since the channel bathymetry and geometry used in verification 

 tests are close to existing (base) condition and the tide of 10 November 1982 

 is representative of the mean tide, the results of WIFM from verification 

 tests were also taken to be those for base condition. They were used accord- 

 ingly in the sediment transport model. The reader should note that the tidal 

 conditions of 10 November 1982 were used in Model A also for base condition. 

 The tide model generated a data file, consisting of tidal elevations and 

 velocities, for each grid cell for each half hour of an approximated semi- 

 diurnal period of 12.50 hr for later use in the sediment model. 



Waves and Wave-Induced Currents 



89. The hydrodynamic models RCPWAVE and CURRENT were extensively tested 

 and compared with analytic solutions, laboratory data, and available field 

 data during their development (Ebersole, Cialone, and Prater 1986 and 

 Vemulakonda 1984) . Considerable experience has been gained previously at WES 

 in field application of these models (Vemulakonda et al. 1985). So reliance 

 can be placed on the results of these models. The models do not require site- 

 specific calibration. Because synoptic field data on waves and wave-induced 

 currents were unavailable for the project area, no separate verification tests 

 were performed for these models except indirectly through sediment model veri- 

 fication. The models were run for the base condition using the same bathjmie- 

 try and channel geometry as in the tidal model. The results of the models 

 were used in verification and base tests of the sediment transport model. 

 Wave climate 



90. One of the primary objectives of the wave and wave-induced current 

 model runs is to furnish input to the sediment transport model. In the case 

 of the sediment transport model, the interest is in sediment transport and 

 yearly shoaling rates in the navigation channel under an average year's wave 

 climate, including normal storms but excluding extreme storms such as hurri- 

 canes and other tropical storms. So the wave climate for an average year 



at the project site was obtained from the WES Wave Information Study (WESWIS)
