Abstract: (8174 Views)
Landslide is considered one of the greatest natural hazards that causes high damage direct or indirect financial every year. One of the areas prone to natural factors in the occurrence of this watershed and from the North Country. One of the occurs Susceptible areas in watershed vaz. Landslide hazard zonation map was prepared by using AHP and 6 certainly factor, landslide index, weight factor, frequency ratio, combination weight factor with landslide index and combination landslide index with AHP. The validate of models showed combination landslide index with weight factor model the value 1.02 was best performance in predicting risk of landslide. Lithology and distance from the road were the most important factors in landslide occurrence. Most statistical models to predict the risk of landslide showed 70 percent of the classes area of landslide risk is related to high risks and very high.
