19. ABSTRACT (Continued). 



application techniques for exploration programs to locate suitable borrow sources for beach 

 fill are reviewed. Techniques for planning, design, and conduct of field exploration 

 programs are recommended based on experiences covering 30 or more years. The main elements 

 of program planning and design are trackline survey layout, core site selection, scheduling 

 of events, selection of equipment and personnel, and preparation of a realistic cost 

 estimate . 



Although presently available exploratory equipment is adequate, and there is consider- 

 able geological experience in correlating subaqueous geomorphic features to occurrences of 

 sand, there is considerable room for improvement in both areas through future research that 

 could materially lower unit costs for beach sand exploratory programs. Since there is a 

 long-term need for beach restoration, continued improvement in geophysical hardware (in 

 particular, computer enhancement techniques) should be pursued.
