JavalancheTM – analyzing hazards to roads

Traditionally, in studying the effect of hazards on roads, a hazard map is prepared based on the hazard in question, the contributing factors and then overlaid with a road map. If the road or a buffer around its vicinity intersects hazard areas, these areas constitute a potential threat. In the approach used in this procedure, imagine traveling along the road and looking to either side for hazards.
