Debris flow susceptibility mapping using a qualitative heuristic method and Flow-R along the Yukon Alaska Highway Corridor, Canada

Research identifies effective methods for mapping debris flow susceptibility along the Yukon Alaska Highway Corridor (YAHC), aiding risk reduction for infrastructure. Two models—qualitative heuristic and Flow-R—were validated using landslide inventories, with the former showing strong correlation in northern regions and the latter successfully capturing known events despite initial parameter uncertainties. The study highlights the potential of these approaches to predict debris flow risks, particularly in areas like Kluane Lake where historical blockages have disrupted transportation.
