Landslide Hazard Zonation Of Khotebesara Watershed In North Of Iran

Abstract

Landslides are significant natural geologic hazard around the world. Landslides cause extensive losses to livelihoods and property and claim many lives. Landslide Hazard Zonation (LHZ) simply means the division and preferably subdivision of a land surface into various zones according to the degrees of actual / potential hazard caused by landslides and related phenomena. In this research LHZ were studied in the Khotbesara watershed in the north of Iran. The ground slope, land use and rock types were used for identification of LHZ. The results showed that 7.3 percent of area is under low LHZ, 3.1 percent is under moderate LHZ, 1.9 percent is under high LHZ and 1.4 percent is under very high LHZ. The main purpose of preparing the Landslide Hazard Zonation maps is to utilize them in future planning in this region.
