In summary, the nourishment requirements for cohesive shores downdrift of 

 harbor structures (or other impediments to alongshore transport) are more 

 complicated than the requirements for similar situations on sandy shores. The 

 requirements must be established on a site-specific basis. They may vary from 

 cases where no beach nourishment is required to others where the natural 

 supply must be completely replaced and/or augmented with coarse grain 

 sediment.
