statistical Wave Data on the Great Lates - A report has been prepared 

 on the Lalce Michigan data and is to be published soon. Reports on the Lake 

 Erie and Lake Ontario data are presently being prepared. 



Correlation of Along Shore Ciirrents and Waves - Preliminary analysis 

 of the data collected at Mission Bay shows that with the very low waves 

 observed (always less than 5 feet and mostly less than 2 feet), the 

 visual observations were not of sufficient accuracy to penult an adequate 

 conparison betireen theory and observation. 



Preparation of Reports Based on Mssion Bay Data - (a) The conpllation 

 of the additional data on leadline survey error has been conpleted and 

 combined lidth the previous report on echo sounder survey error to be 

 published as a Board Technical tfemorandura. (b) An analysis of a number of 

 profiles x-fas prepared by the Danish engineer Per Bruun on his .visit here and 

 a conparlson made with Danish data. 



Study of Pressures Developed by Waves Breaking Against Vertical 

 Structures - A few additional tests x^rere run, and the entire set of data is 

 being analysed and a report being prepared. 



Manual on Wave Forecasting - A manual giving the latest and most 

 accurate riBthods of applying the Sverdrup-Mank- Bret Schneider curves for 

 all types of X'jeather and wave conditions involving both moving and 

 stationary fetches is being prepared. 



In addition to the above, project reports on the Equilibrium Profile 

 of Beaches, A laboratory investigation of the Vertical Rise of Solitary 

 Waves on Impermeable Structures and the Study of the Quantity of Sand in 

 Suspension in Coastal Waters have been conpleted and are being edited for 

 publication ard distribution as Beach Erosion Board Technical I'fem.oranda, 



AnalysivS of the data on the Correlation of Effectiveness of the 

 South Lake Worth Inlet By-passing Plant and The Study of Effects on Beach 

 Profiles of Varying Wave Periods has been completed and reports are being 

 circulated to the staff for com^iEnt prior to publication.
