three Southern California beaches is described, the need for more 

 research as to the effectiveness of such structures is suggested, and 

 other possible uses of long groins are discussed.

Groins produce various effects on different shorelines; design 

 data are sparse, so experience and judgment become important design 

 skills to a greater degree than in most engineering problems. Court 

 decisions are described which, from the engineering standpoint, seem 

 opposite in effect where physical conditions were similar. The con- 

 clusion is made that the engineer who undertakes projects including 

 seacoast groins needs legal counsel, special engineering knowledge 

 and experience, and a healthy respect for the continuing acceptability 

 of the client's seacoast groins to neighboring proprietors.

Basic principles bearing on the nature of beaches and processes 

 that act to modify them are considered in light of present coastal 

 development demands. A working hypothesis is developed that applies 

 the principle of the conservation of mass to the mechanics of granular - 

 fluid media. This hypothesis appears to have general application to 

 sand transport processes in the littoral zone. Additional research 

 must be done to provide basic information in some critical areas 

 before application can be made with assurance.
