Currents on Headlands to the Control of 



Shore Erosion by Groins" 



Evans, 0. F., Proceedings of the Oklahoma 



Academy of Science , 1943, pp. 9-13. 



Contrary to general opinion, the author believes that beach drifting 

 is a more important source of sediment transportation by waves and 

 currents than are littoral currents. Groins are discussed and improve- 

 ments are noted. A permeable groin is suggested which eliminates the 

 need for expensive preliminary surveys.

Pictorial article relies upon photography showing "before and after' 

 conditions where groins of recent type have been installed. Discussion 

 is related to both ocean and Great Lakes riparian studies. Structural 

 criteria of groins and the effects of artificial interference of the 

 littoral drift are discussed.
