available Information on examination surveys for the navigation channel, we 

 were able to locate only one set of examination surveys covering a period of 

 approximately 1 year (1980 through 1981) which was free from the effects of 

 dredging and severe storms. The duration of this data set is too short for 

 the data set to be used for strict verification of Model B results which are 

 based on 20-year hindcast wave data. Therefore, a strict verification of 

 Model B results with the data set is not possible. Instead, the average 

 yearly erosion/deposition rates along the channel obtained from the data set 

 will be compared with Model B results to see if the numerical model results 

 are reasonable and agree with the trends and shoaling magnitudes exhibited by 

 the field data. 



106. Prototype data. The field data set consisted of seven examination 

 surveys conducted by CESAJ during 1980 and 1981 between sta -80+00 and 

 sta 325+00 (Figure 19). For convenience, this pre-1985 CESAJ stationing will 

 be used throughout this report. The locations and dates of the surveys are
