Abstract A morphological model for estimating ground‐ice contents of various landscape units is presented to address the gap between large‐scale, general studies and small‐scale, site‐specific case histories. The model considers different ground‐ice types and cryostratigraphic relations between ice bodies within a terrain unit. Input parameters needed for the model are described. Derived variables and algorithms used to determine the quantity of each ground‐ice type within a terrain unit are presented. Examples of the application of the model are provided for the Yukon Coastal Plain, northwest Canada. The uncertainties and limiting assumptions of the model are discussed.
