Figure 24. BEP data processing. 



The values for AS and AV are limited in two significant ways (see 

 Figs. 25 and 26). The lower limiting elevation of the surveys for computa- 

 tional purposes is MSL and therefore the values do not provide any indication 

 of changes below MSL. The volume computations are also based on a landward 

 boundary, common to most of the surveys, for each profile line. As a result 

 of these two limiting factors, there generally exists a landward region of 

 change as well as the probably more substantial below-MSL region of change 

 which are not included in the computed volume.
