Abstract
This research examines monthly aeolian processes in the Seward Sand Hills of southwestern Saskatchewan. A detailed analysis of three dunes was conducted over a period of twenty months. Currently many of the aeolian landforms in the Seward Sands Hills are stabilized. Localized activity in the form of blowouts and active parabolic dune heads occur sporadically throughout the area due to localized aridity, microtopography and microclimate. Blowout dunes form relatively quickly and represent the only type of aeolian activity capable of forming under recent (past 150 years) conditions. Active parabolic dune heads represent the process of slow stabilization of former full-scale parabolic dunes. Dune activity is a function of the presence or absence of supply-limiting and/or transporting-limiting factors. Early winter to early spring was the period of maximum aeolian activity in the Seward Sand Hills. Significant amounts of erosion and deposition occurred during most months as a result of the constant migration of secondary bedforms within the active layer of the dunes. However, all dunes experienced very little net forward migration.
