ARCTIC SLOPE PROTECTION METHODS

Craig B. Leidersdorf, Peter E. Gadd, William G. McDougal

Abstract


This paper reviews knowledge acquired in the Alaskan Beaufort Sea pertaining to three methods of Arctic slope protection: (1) sacrificial beaches, (2) "soft" (geotextile based) armor, and (3) linked concrete mats. Design considerations and performance evaluations are presented for each method, along with recommendations for future use. It is concluded that the existing technology is capable of providing reliable protection for structures located in coastal and nearshore areas, and that more durable systems will be required to withstand the extreme wave and ice loads which can occur at exposed sites in deeper waters.
