This is an extensive research paper covering such aspects as 

 theoretical and statistical analysis of longshore transport be- 

 havior of sediment movement, sediment balances, and determination

 mechanisms is outlined. Though groins are not explicitly discussed, 

 structures are discussed which act similar to groins.

 paper.
