This paper presents history, problems, construction and current 

 results concerning critical condition of shore erosion, unstable 

 inlets, and coastal inundation along the Long Island coast. Groin 

 construction and resultant effects are discussed.

This paper describes works to improve and stabilize the Dubai 

 Creek entrance located on the Arabian Gulf Coast. As part of the 

 project a groin (jetty) was constructed to protect the entrance and 

 to encourage accretion. Maps show accretion as the different phases 

 of the project are completed.

A mathematical theory for predicting sand wave formation was 

 tested in the field, and showed that groins totally reflect the sand 

 wave. The amplitude of the accretion and erosion at the spot of the 

 first groin becomes twice the accretion and erosion where no groins 

 had been constructed.
