 GEOPHYSICAL PROBLEMS IN APPLIED SEDIMENTATION

One approach to problems in applied sedimentation cuts across the 

 lines of development of the geophysical sciences. In following this 

 application it is important to avoid the many preconceptions and 

 prejudices one encounters in approaching geophysics for the first time. 

 Many problems in applied sedimentation will benefit by the use of 

 geophysical methods, but there is great danger in assuming that geo- 

 physics will provide a perfect solution. The history of many phases 

 of geophysical science has been repeated too often: first, a brilliant 

 idea showing exceptional promise of success, without practical limita- 

 tions; second, an extravagant program of application without ade- 

 quate buttressing of the contributory sciences; third, the inevitable 

 disappointment following the misguided application; and, finally, a 

 wholesale condemnation of the method employed, perhaps of geo- 

 physics entirely. 



It is difficult to understand why some applications of geophysics 

 have been developed in a scientific manner to produce valuable results, 

 whereas other equally important applications have followed the un- 

 happy course outlined above. Some people become emotional about 

 geophysics. Either they ride the crest with unbounded enthusiasm, 

 or they sink to the depths of despair when confronted with failures. 

 This pattern has been retraced altogether too often during the past 

 three decades for it to be passed by without comment. It is hoped that 

 these remarks may spare the reader from similar unprofitable experi- 

 ences. 



Geophysics is no panacea. It has purpose, scope, and limitations. 

 It can be used to advantage for many problems, and the overall costs 

 are usually favorable. Its successful use involves broad knowledge 

 and experience in many sciences. Strictly speaking, there is no single 

 department of geophysics. It transcends the boundaries of many
