Abstract
This paper resulted from studies on 1:50000 scale topographical, 1:250000 scale geological and 1:250000 scale land use maps and meteorological and hydrometrics station data for road safety proposes considering environmental hazards parameters. We overlay table and map data layers considering spatial distribution, time and severity of hazards effect and then after field surveys, based on evidences and all of our data many maps of geological sensitivity, climatic, hydrologic and geomorphologic hazards produced. Finally by collating three above-mentioned maps, final map of environmental hazards of Sanandaj- Marivan road was produced. We conclude that about 65 percent of the road is passing over very high risk areas, 25 percent over high and 10 percent over mid risk areas.
