Abstract: Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation of ice forces on port and coastal structures is an integral part of design in relationship with tides, currents, coastal processes and freezing index, among other factors. These interrelationships are discussed and quantified in relation to design applications using the best information now available. Various concepts and types of structures with potential for use in ice environments are presented.
