the hindcast values with those recorded at Long Branch, New Jersey has been 

 made by applying a refraction analysis to the deep water hindcast data, and 

 the agreement is quite adequate. 



Study of Methods of Sand .Analysis by Settling Tube - The Visual 

 Accumulation Tube has been received from the St. Paul District and erectedj 

 tests will be undertaken to determine its adaptability to the needs of the 

 Board for the size analysis of beach sands. 



Analysis of Moving Fetches for Wave Forecasting - A report on the 

 methods of forecasting waves from moving fetches has been completed and 

 is scheduled to be published early in 195h» 



Pro.ject ESMOND - The laboratory testing for this project is complete 

 and a report is being prepared. The results generally indicate that, of 

 all the sounding lead shapes tested, a spherical shape offers the best 

 possibilities for an improved sounding lead in soft sediments. 



Study of Effect of Tsunamis - The draft of the preliminary report is 

 completed and under review. The tests described previously have in- 

 dicated that relative run-up (R/H, where R is the maximum vertical rise and 

 H is the wave height at the toe of the slope) increases with a decrease in 

 wave steepness (H/L where L for these tests is defined as the horizontal 

 distance from the first noticeable rise of water above the still water 

 level to the point of maximum wave crest height) . Tests are being con- 

 tinued to relate the wave height H as measured above to the wave height 

 at the shore line. 



Routine progress^ testing, and analysis has been made on the other 

 projects being carried out by the Research Division. A project report by 

 G. M. Watts "A S^udy of Sand Movement at South Lake Worth Inlet, Florida" 

 was published as Technical Memorandum Mo. 3h 3 and papers on "Hindcast 

 Wave Statistics for the Great Lakes," "Field Investigations of Suspended 

 Sediments in the Surf Zone," and "Pressure of Breaking Waves on Vertical 

 Structures" were prepared and presented by T. Saville, Jr., G. M, Watts, 

 and C„ V. Ross respectively at the Fourth Conference on Coastal Engineering! 

 these papers will be published in The Proceedings of this meeting.
