 either the low, impermeable, nonadjustable groin or the impermeable, 

 adjustable type.

A section of coastline on the southern tip of India was subject 

 to increasing amounts of erosion. A breakwater and an 11-element 

 impermeable groin system were constructed as an experiment. Labora- 

 tory model experiments were also made. Observation of the structures 

 in field and laboratory led to proposed advantageous construction of 

 protective structures along other parts of shoreline where erosion 

 was eminent .

Compression of wet or "running sand" can be produced by correctly 

 designed groins, resulting in the stabilization of beaches. According 

 to the authors, groins must be impermeable, substantial in construction 

 so that they can withstand the longitudinal thrust of stabilized beach 

 material, and high and long enough so that beach material will not be 

 lost over or around them.
