Modification and Layout of the Galveston Island Groin Field for Retaining Sand on Beach

In the past hundred years or so, numerous groin fields have been constructed along the world’s coastline. Many of these have little or no existing beach in the groin field. This paper suggests a method for retaining sand in the groin field by moderately modifying the existing groin system. The application of this method is illustrated for the case of the Galveston groin field.
