"The Danish Westcoast: Littoral Drift 5008GR0001 



Problems and Measures Against Coast Erosion"

London, Vol. 31, No. 359, Sept., 1950, pp. 



163-167. 



Coastal protection structures, including groins, built on the 

 west coast of Denmark are reviewed for the period from 1870 to 1950. 

 The author gives an example of interest, noting that impermeable 

 concrete-block groins have been sinking due to their great weight, 

 and must be heightened periodically. Construction costs, structural 

 design, and maintenance of structures are given.

Successful operation of groins depends on length and spacing of 

 groins where impounded sediment will form a saw-toothed coast-line or 

 a series of closed bays.
