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

 in Water, 1941. 



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

 Waves, 1941. 



Technical Report No. 3 — An Experimental Study of Submarine 

 Sand Bars, 1948. 



August 1948. 



This paper was prepared for the Beach Erosion Board during World 

 War II by Dr. Garbis H. Keulegan of the Hydraulics Laboratory of 

 the National Bureau of Standards. Dr. Keulegan completed work 

 for this paper in 1944 while detailed to the Beach Erosion Board as a 

 consultant in hydrodynamics. While this paper was prepared pri- 

 marily for departmental use and the opinions and conclusions ex- 

 pressed are those of the author, it is believed that it will be of material 

 value to engineering and research agencies engaged in work involving 

 submarine sand bars.
