Section 8. BULLETINS OF THE COASTAL ENGINEERING RESEARCH CENTER 



Volume I (1964) 



Establishment of the Coastal Engineering Research Center 



Public Law 172, enaci ad by the 88th Congress and approved 

 7 November 1963, established the Coastal Engineering Research Center 

 as successor to the Beach Erosion Board. A brief chronology de- 

 scribes the legislative changes relating to the Beach Erosion Board 

 throughout its 33-year history. 



A Selected Bibliography and Brief Review of the Theory and Use of 

 Tracers in Sediment Transport Studies by Cy r i I J . Ga I v i n , Jr. 



The review treats kinds of tracers, theoretical models of tracer 

 movements and model deficiences, and the applications of tracers. 

 The bibliography consists of 20 items critically selected from about 

 130 references held in the CERC technical library. 



A Theoretical Distribution of Waiting Times for Tracer Particles 

 on a Sand Bed by Cyril J. Galvin, Jr. 



A distribution of waiting times for the probabilistic motion of 

 tracer particles is developed for a model which includes deposition 

 as well as erosion. The mathematical description of this model 

 accounts for the buried, exposed, and eroded quantities of tracer 

 as a function of time. Includes an appendix,, "Mathematical 

 Derivation of Erosion-Deposition Model" by B. E. Fristedt. 



Comparison of the Bretschnei der Relations Between the Distribution 

 of the Visible Waves and the Spectrum of the Sea Waves by Analysis 

 of Wave Records from the Deutsche Bucht by Jurgen Piest 



The results of analysis of eight sea-wave records taken near 

 the Mellum Plate Lighthouse are used for investigating the relations 

 found empirically by C. L. Bretschneider (1959). The general relation 

 between the two-d imensiona I distribution of the visible waves and 

 the spectral distribution of the swells, introduced by Bretschneider, 

 has been qualitatively confirmed. The linearity of a definite re- 

 gression function, found empirically by Bretschneider, however, coulc 

 not be verified. 



Stabilization of Shingle Alluvial Shores by Groins of Full Profile 

 by A. M. Zhdanov, transi ated and abstracted by 0. W. Kabelac, CERC. 



Presents a formula for determining dimensions in the design 

 of groins. Model tests are correlated with observations in the 

 prototype. A design example is presented.
