13. ABSTRACT (Maximum 200 words)
Physical modeling is often used to study complex ice processes when analytical formulations or numerical
simulations fall short. Judicious choice and use of materials to model the ice in scaled experiments requires
knowledge of the properties of the material as well as an understanding of the dominant forces governing the
process to be modeled. This report describes general similitude requirements for various modeling situations
and the properties of several previous and currently used model ice materials.
