"The Selsey Coast Protection Scheme" 6112GR0001 



Duvivier, J. , Journal of the Institution 

 o£ Civil Engineers, London, Vol. 20, Dec, 

 1961, pp. 481-506. (TC257 .D2) 



Because of threatening erosion or inundation or both, a scheme 

 was undertaken to construct protective structures, including groins, 

 on the coast east and west of Selsey Bill, England. This paper gives 

 the history of erosion, trends of littoral transport and currents, 

 sediment supply sources, scheme of protective works, and results after 

 construction. 



A new type of articulated groin built with transverse and longi- 

 tudinal flexibility is discussed, and its satisfactory performance 

 noted. Measures taken to combat erosion beyond the terminal groin 

 are presented.
