Case groins, constructed of timber, with a long, low design, and 

 economical to build are discussed relative to groins of other designs. 

 A field study is presented in favor of Case groins where the author 

 states that an analogy of small obstructions (Case groins) and the 

 multiplication of small results gradually brings about desired beach 

 buildup.
