Abstract: Because of the very fast progress in ice engineering in the last few years this paper is limited to two topics of ice engineering where new developments are dominant. In river and lake ice engineering the following new developments are discussed: intake design against frazil clogging, new types of ice booms and new methods to alleviate ice jams (comprising ice trenching and the use of air cushioned vehicles). For sea and Arctic ice engineering the broad question of ice management in harbors is discussed. A general presentation is made of the fundamental concepts of harbor design against ice blockage, including the design of external ice barring structures. New local ice control measures inside the harbor are also reviewed: use of thermal discharge, air jets, flow developers and ice clearing by ships. Finally, the design of ice barring structures and dikes is discussed.
