sensitivity to damage, variable analysis, ice distribution in land systemsAbstract
An extensive land classification for the Mackenzie River valley has been combined with an: analysis of synergistic systems to quantify field units for a more comprehensive terrain evaluation than could have been produced by either field or analytical work alone. The empirical prediction of ice conent and its distribution within different environments has been used with field data to develop a classification for sensitivity of the landscape to damage from disturbance. The zone of most rapidly changing sensitivity which occurs around Fort Norman and Norman Wells ąs the Discontinuous merges into the Continuous Permafrost Zone has been quantified.
