II-A "Wave Refraction at Long Beach and Santa Barbara, California" 

 C by Dean M. P. O'Brien, University of California, May 1947. 



Examples of wave refraction analysis are presented and 

 discussed which offer rational explanations of unusual 

 observations at Long Beach and Santa Barbara, California. 



II -C "A Formula for the Calculation of the Tidal Discharge Through 

 an Inlet" by Dr. Garbis H. Keulegan, National Bureau of 

 Standards and J. V. Hall, Jr., Beach Erosion Board Staff 



A formula for maximum discharge through an inlet based on 

 a known tidal prism is developed and checked for four 

 locations where measured plans have been made. 



II-A "Characteristics of Measured Wave Action on the Basis of the 

 Frequency Distribution of Wave Length, Wave Height and 

 Steepness" by H. Ehring, 1940 



Translation of a paper originally published in German. 

 Classification of wave data measured by wave gages 

 according to frequency of occurrence of various classes 

 of wave dimensions rather than by a mean or particular 

 value is discussed. Examples and advantages are given. 



II-A "Couiite Central d'Oceanographie et d'Etude des Cotes" 

 F 



Briefs of information of general interest contained in 

 periodic information bulletin of the above French organi- 

 zation. Includes "Remarks on Wave Forecasting", "Relations 

 Between Microseismic Activity and Waves", "Wave Diffraction", 

 and "An Explanation of Certain Marine Currents".
