A spatial framework for modeling hazards to transportation lifelines

Transportation networks are exposed to a wide range of natural hazards and this study has developed a GIS tool for analyzing these hazards. The primary hazards included in this study are avalanches, landslides, flooding, earthquakes, wildfires, and rockfall. The GIS software used was MFWorks
