Abstract
Accelerated erosion rates following a wildfire event alter the landscape and pose a concern in previously undisturbed forest areas in steep terrain. Wildfire has been found to alter the soil structure and soil aggregates, which in addition to the loss of vegetation and the presence of hydrophobic layers, enhances the effect of decreased infiltration by increasing overland flow and slopewash erosion. These processes can affect the landscape for one to three years. To date, numerical model applications have not generally considered the role of wildfire. The purpose of this research was to incorporate a wildfire component into an existing landscape evolution model, LandMod, to analyze sediment transport and deposition in an Interior Rain Forest drainage basin of British Columbia following wildfire disturbance.
