This is a progress report on the Homer Spit Beach Erosion Study. 

 Information is presented regarding the rapid acceleration of the 

 erosion processes due to the subsidence of Homer Spit during the 

 27 March 1964 earthquake. The effect on existing groins both before 

 and after the quake are discussed. Immediately after the quake, 

 emergency measures were required to prevent wave and high water 

 damage to existing structures on the spit. An evaluation of the 

 effectiveness of these measures is presented along with basic data 

 gathered from the study and some of the problems encountered.

Describing the various uses of gabions, this article includes a 

 discussion on their usefulness in groin construction. Providing a 

 semi-permeable structure, the use of gabions is especially advan- 

 tageous where scour may occur on the downdrift side of the groin.

Presented is a method for investigation of groin effectiveness 

 which represents progress toward a solution of a controversial problem. 

 Experimental methods in the use of dyed sand are described. The results 

 are presented as examples of changes in submarine relief, changes in 

 current fields, and distribution of dyed sands. The results indicate 

 the correctness of this approach to an investigation of this type.
