Environmental and Geomorphological Hazards Assessment and their Role on Road Transport (Case Study: Col Almass)

Abstract

Road transport plays a key role in the effective implementation of national sustainable development plays and safety of traffic during the year. Of special importance are Col Almass Anklet and Esalam in the western Alborz 30 km long road. This way of connects sections steep and passes high-risk areas and always threatens types of risks, especially in the range of movement types. Established lines of communication and identification of natural risks and geomorphic effects of road accidents caused by geomorphologic factors is a main issue The relationship between climatic phenomena, road accidents and the high-risk areas is studied which can provide suggestions and solutions to improve road transport safety factors. In one of the axes, the axis connecting the north of the country Esalem-Khalkhal (Col Almass) are included in the study. Methods are based on field observations and interpretation of these observations, geological and topographic maps, aerial photographs. In addition, a risk zoning map of the area showed geomorphologic 64 percent of association is high and very high risk. Geomorphologic assessment conducted in this study, shows damage to roads and other facilities in the area.
