Abstract
The quantitative study of the geomorphology of large regions has been neglected due to the large amounts of data that are necessary for such an undertaking. Technological advancements now permit rigorous regional analyses. A GIS is well suited to the storage and manipulation of the quantity and quality of data required. The ARC/INFO GIS has been employed here as the primary tool to facilitate an assessment of the geomorphic susceptibility of the Palliser Triangle region of southwestern Saskatchewan. Geomorphic response units (GRUs) have been proposed as the basic units of subdivision for the region. The theory behind these units has been developed through a synthesis of the literature and GRUs have been mapped for a portion of the Palliser Triangle and rated according to geomorphic sensitivity (defined here as susceptibility to water erosion). Two sensitivity maps have been produced using variations of the same equation. Both maps indicate groups of highly susceptible GRUs in areas characterized by moderate topographic complexity. The resolution of these maps is too coarse to identify small scale features such as individual dunes of the Great Sand Hills and too fine for use at a smaller scale. The methodology promoted by this research allows the application of geographic information systems to assessments of landscape evolution.
