Ice Engineering
Ice Engineering is published in accordance with AR 25-30 as one of the information exchange functions
of the U.S. Army Corps of Engineers. It is primarily intended to be a forum whereby information on ice
engineering work done or managed by Corps field offices can be disseminated to other Corps offices, other
U.S. Government agencies, and the engineering community in general. The purpose of Ice Engineering is
information exchange and not the promulgation of Corps policy; thus, guidance on recommended practice in
any given area should be sought through appropriate channels or in other documents. This report's contents
