 between 1.0 and 2.0 m) . This pattern is interrupted in the immediate vicinity 

 of the pier where a trough runs under much of the pier's length, ending in a 

 scour hole at the pier's seaward end where depths are up to 3.0 m greater than 

 the adjacent bottom. 



Sediment Size 



17. Dune sediments are generally composed of medium size sand and are 

 moderately to well sorted. On the beach face and the beach step, size dis- 

 tribution is primarily bimodal, with a very coarse (1-2 mm) gravel intermixed 

 with fine to moderate size sand. Offshore, sediments are well sorted, and 

 size decreases with the distance offshore.
