ment of the beach profile as predicted by the numerical model was as follows. 

 The first increase in water level resulted in the formation of an almost 

 stationary emergent bar, as observed in the first few profiles. As water 

 level dropped, the break point rapidly moved seaward, and the bar correspond- 

 ingly moved in the seaward direction. When the water level increased at later 

 cycles and a well -developed bar existed at the seaward end of the profile, 

 waves passed over the bar and broke inshore creating a small second feature 

 just shoreward of the main breakpoint bar.

464. As observed on the measured profile, a small berm formed on the 

 foreshore during the latter part of the run which was not described by the 

 model. Otherwise, the model reproduced the main shape of the beach profile, 

 that is, a main breakpoint bar with a smaller bar-like feature inshore, 

 separated by a distinct trough. Locations of calculated bars were somewhat 

 farther seaward compared with those of the measured profile, but bar volume 

 was reasonably well predicted.
