Abstract

Mountainous country like Nepal is highly susceptible to the geo-hazard like landslide. Due the drastic variation into the topography there exists steep-gentle slope with their variation there found several types of hazards related to the topography, soil, rock and various intensity of rainfall. In this study model output in the form of landslide hazard map has been evaluated by correlating training landslide and validating landslide. The study shows that 12% of Beni to Lete road section of the Kaligandaki corridor have very high hazards, 27% of the area of Beni to Lete road section in high hazard, 30% of the area lies in the moderate hazards, 24% of the area lies in low hazard zone and 7% of the area of Beni to Lete road section lies in the very low hazard area. The study concludes that effect of geology is highest among all factors and is followed by elevation and drainage proximity. The phyllite and augen gneiss rich rock unit has found more suffered landslides which indicate reasonable predictive capabilities compared to other work of this nature.
