Technical Report No. 1 — A Study of Progressive Oscillatory Waves 

 in Water. 



Technical Report No. 2 — ^A Summary of the Theory of Oscillatory 

 Waves (in preparation) . 



The authority for publication of this report was granted by an act 

 for the improvement and protection of the beaches along the shores 

 of the United States, Public, 834, 74th Congress, approved June 

 26, 1936. 



This paper reports the results of the fii'st of a series of experiments 

 adopted by the board in 1939. It deals with the basic characteristics 

 of oscillatory wave motion m water. The experimental work was 

 under the direction of Lt. William C. Hall, C. E., and the report was 

 prepared by Dr. Martin A. Mason, Chief of the Research Section, 

 Beach Erosion Board.
