Landslide Risk and Hazard Zonation
Author(s):
Abstract:
This paper has focused on landslide hazard and risk zonation in the critical Ziarat watershed. Varnes equation and combination of Hazard map، elements at risk map and vulnerability map were used in the preparation of the risk map. Two quantitative models، including multivariate statistical (logistic regression) and LNRF model were used in the preparation of the hazard map. After applying the rate to the classes of parameters، Landslide hazard zonation was prepared for each of the models. The prior model was selected using four indices، including Quality summation (Qs)، Precision of the predicted results (P)، Receiver Operating Characteristic (ROC) and Chi-Square test and used in preparation of risk zonation. Results indicated that the logistic regression model shows a better performance for landslide hazard zonation and 13. 63 and 9. 04 percent of Ziarat watershed –including Ziarat village– were located in a high and very high zone of hazard and risk maps respectively.
