Volume 1, No. I (Continued) 



Charts and Tables for Determining Surface Stone Sizes for Rubble 

 Mound Structures in Wave Action 



Application of the Iribarren formula as mod if ied by Hudson to 

 make it dimensionally homogeneous is discussed for both surface and 

 subsurface stones. Charts and Tables facilitating solution of the 

 basic equation are presented. Written by Wm. H. Vesper and Kenneth 

 Kaplan, Beach Erosion Board staff. 



Japanese Research in Physical Oceanography, 1948-1950 



Information prepared by Dr. Koj i Hidaka, Geophysical Institute, 

 Tokyo University summarized research etforts in physical oceanography 

 in Japan. Japanese agencies involved with the program, periodicals 

 and journals issued by Japanese institutions and societies, and a 

 list of Japanese references are also included. 



SPECIAL ISSUE No. 2 - March 1955 



Shore Protection Planning and Design (Preliminary Issue) 



A preliminary printing of Technical Report No. 4 distributed to 

 obtain constructive comments from Interested engineers. This Special 

 Issue became obsolete when the first edition of T.R. 4 was published 

 in 1954. 



Volume 7, No. 2 - Apri I 1955 



The Reflecting Power of Maritime Works Exposed to Action of the Waves 



An abstract of a translation of a French paper by M. Miche, 

 originally appearing In the Annals of the Highway Department, 

 National Press in June 1951. Mr. Miche's work is an extension of 

 the work of Iribarren and Nogales reported In Volume 5, No. 2 of 

 the Bulletin. Relationships useful In design for determining the 

 amplitude of the reflected wave for particular incident waves and 

 types of slopes of the intercepting structures are evolved. 



Notice of Publication for New Method of Drawing Wave Refraction 

 Diagrams 



The new method Is described and a drawing of the protractor to 

 be used is included. The new method is considered to be simpler 

 and quicker at no sacrifice in accuracy than other methods in 

 general use. The article, entitled "The Direct Construction of 

 Wave Rays" by R. S. Arthur, W. H. Munk and J. D. Isaacs, was 

 published In Transactions of the American Geophysical Union, 

 December 1952.
