and does not extend to the model results for the rest of the study area. 



123. In terms of yearly shoaling volumes, if the reach of channel from 

 sta -80+00 to sta 325+00 is considered, the results translate to approximately 

 475,000 cu yd/year for base and 788,000 cu yd/year for Plan 1 allowing for the 

 wider Plan 1 channel, or an increase of approximately 66 percent from base to 

 Plan 1 . The base volume is of the same order as the maintenance dredging vol- 

 umes recorded in CESAJ dredging logs.
