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

Sediment Size 



17. On the dunes, sediments are generally medium size and moderate to 

 well sorted. On the beach face and the beach step, size distribution is pri- 

 marily 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.
