The purpose of this investigation, made at the request of the 

 Beach Erosion Board, was to obtain information on the comparative 

 action of permeable and impermeable groins presently employed to 

 promote accretion and stabilization of beaches where littoral transport 

 induced by wave action is a significant factor.

Shore protective structures, including groins, along the New Jersey 

 coast are discussed and evaluated. New designs are offered where shore 

 conditions warrant special structures.
