			TOTAL SAND THROUGHPUT FOR 1996 (m3) =2318
* 1996 value,  extrapolated value;   summer value.


Table 3 lists the extrapolated or averaged daily throughput values and calculated total 
throughput for various conditions using frequencies of occurrence for typical summer and 
winter surf conditions. The 1996 samples were taken under S3, S6, W3 and W6 throughput 
conditions and values for these measurements were substituted for the Table 2 means for 
these conditions for the calculations shown in Table 3.
