The Wind Element in Beach Erosion 



A paper presented at Symposium on Hydrometeorologica I Problems, 

 American Geophysical Union, May 1950 by Martin A. Mason. The role 

 of the wind in removing sand from the beaches is discussed, and rela- 

 tive importance of effects of wind-generated water waves and direct 

 effects of the wind on the shore face is discussed. Relationships 

 of wind velocity and sand movement developed by other investigators 

 are given. 



The Lag and Reduction of Range in Tide Gage Wei Is 



Theoretical analysis and experimental study of the problem of 

 lag of high and low water and reduction of range in a tidal gage 

 we I I are presented. Theoretical curves are concluded to be more 

 reliable because error in the experimental results is relatively 

 great. Written by M. P. O'Brien.

Munch-Petersen's Littoral Drift Formula 



Translation of a paper presented by Sv. Svendsen before the 

 Association of Government and Harbor Engineers at Helsingfors in 

 August 1938. A formula developed by the late Danish Professor Munch- 

 Petersen giving the mater ia l-movi ng power of the waves at a point on 

 the coast in terms of wind speed and frequency, available fetch 

 lengths and direction, and a constant to be evaluated, is presented, 

 discussed, and examples of its application to North and Baltic Sea 

 Coasts g i ven. 



Surging in Depoe Bay, Oregon 



A report by Willard Bascom, University of California, describes an 

 unusual surging condition occurring in Depoe Bay Harbor in October 

 1947. Measurements were recorded 



Stereophotogrammetr ic Wave Measurement 



A report by Lewis A. Dickerson, U. S. Army Map Service, on in- 

 vestigations and experiments to determine feasibility of measuring 

 heights of ocean waves by photogrammetr ic means. Use of this method 

 is concluded to be possible, but extremely difficult.
