19 ABSTRACT (Continue on reverse if necessary and identify by block number) 



Beach restoration as a means for mitigating severe storm damage is a major coastal 

 engineering activity in the US Army Corps of Engineers. The single most important element 

 in beach restoration is the availability of sand on a beachfront that is both suitable from 

 an engineering standpoint and stable. Since local financial participation is now legally 

 required on beach restoration projects, improving the efficiency of preconstruction explora- 

 tion and design techniques has become exceedingly important in overall project management. 

 This study is the first of a series that will examine the state of the art of the various 

 geotechnical and geological technologies used to foster effective and environmentally sound 

 coastal project designs. 



The current state of knowledge regarding geological indicators of subaqueous, sand- 

 bearing formations is discussed. Existing technology in terms of geophysical equipment and
